+
+<h2 id="can-we-preserve-segments-from-compaction">Can we preserve Segments from Compaction?</h2>
+<p>If you want to preserve number of segments from being compacted then you can set the property
+ <strong>carbon.numberof.preserve.segments</strong> equal to the <strong>value of number of
+ segments to be preserved</strong>.</p>
+<p>Note : <em>No segments are preserved by Default.</em></p>
+
+<h2 id="can-we-disable-horizontal-compaction">Can we disable horizontal compaction?</h2>
+<p>Yes, to disable horizontal compaction, set <strong>carbon.horizontal.compaction.enable</strong>
+ to <code>FALSE</code> in carbon.properties file.</p>
+
+<h2 id="what-is-horizontal-compaction">What is horizontal compaction?</h2>
+<p>Compaction performed after Update and Delete operations is referred as Horizontal Compaction.
+ After every DELETE and UPDATE operation, horizontal compaction may occur in case the delta
+ (DELETE/ UPDATE) files becomes more than specified threshold.</p>
+<p>By default the parameter <strong>carbon.horizontal.compaction.enable</strong> enabling the
+ horizontal compaction is set to <code>TRUE</code>.</p>
+
+<h2 id="how-to-enable-compaction-while-data-loading">How to enable Compaction while data
+ loading?</h2>
+<p>To enable compaction while data loading, set <strong>carbon.enable.auto.load.merge</strong> to
+ <code>TRUE</code> in carbon.properties file.</p>
+
+<h2 id="where-are-bad-records-stored-in-carbondata">Where are Bad Records Stored in CarbonData?</h2>
+<p>The bad records are stored at the location set in carbon.badRecords.location in carbon.properties
+ file.<br>
+ By default <strong>carbon.badRecords.location</strong> specifies the following location <code>/opt/Carbon/Spark/badrecords</code>.
+</p>
+
+<h2 id="what-are-bad-records">What are Bad Records?</h2>
+<p>Records that fail to get loaded into the CarbonData due to data type incompatibility are
+ classified as Bad Records.</p>
+
+<h2 id="can-we-use-carbondata-on-standalone-spark-cluster">Can we use CarbonData on Standalone Spark
+ Cluster?</h2>
+<p>Yes, CarbonData can be used on a Standalone spark cluster. But using a standalone cluster has
+ following limitations:</p>
+<ul>
+ <li>single node cluster cannot be scaled up</li>
+ <li>the maximum memory and the CPU computation power has a fixed limit</li>
+ <li>the number of processors are limited in a single node cluster</li>
+</ul>
+<p>To harness the actual speed of execution of CarbonData on petabytes of data, it is suggested to
+ use a Multinode Cluster.</p>
+
+<h2 id="what-versions-of-apache-spark-are-compatible-with-carbondata">What versions of Apache Spark
+ are Compatible with CarbonData?</h2>
+<p>Currently <strong>Spark 1.6.2</strong> and <strong>Spark 2.1</strong> is compatible with
+ CarbonData.</p>
+
+<h2 id="can-we-load-data-from-excel">Can we Load Data from excel?</h2>
+<p>Yes, the data can be loaded from excel provided the data is in CSV format.</p>
+
+<h2 id="how-to-enable-single-pass-data-loading">How to enable Single Pass Data Loading?</h2>
+<p>You need to set <strong>SINGLE_PASS</strong> to <code>True</code> and append it to
+ <code>OPTIONS</code> Section in the query as demonstrated in the Load Query below :</p>
+<pre><code>LOAD DATA local inpath '/opt/rawdata/data.csv' INTO table carbontable
+OPTIONS('DELIMITER'=',', 'QUOTECHAR'='"','FILEHEADER'='empno,empname,designation','USE_KETTLE'='FALSE')
+</code></pre>
+<p>Refer to <a
+ href="https://github.com/PallaviSingh1992/incubator-carbondata/blob/6b4dd5f3dea8c93839a94c2d2c80ab7a799cf209/docs/dml-operation-on-carbondata.md">DML-operations-in-CarbonData</a>
+ for more details and example.</p>
+
+<h2 id="what-is-single-pass-data-loading">What is Single Pass Data Loading?</h2>
+<p>Single Pass Loading enables single job to finish data loading with dictionary generation on the
+ fly. It enhances performance in the scenarios where the subsequent data loading after initial
+ load involves fewer incremental updates on the dictionary.<br>
+ This option specifies whether to use single pass for loading data or not. By default this option
+ is set to <code>FALSE</code>.</p>
+
+<h2 id="how-to-specify-the-data-loading-format-for-carbondata">How to specify the data loading
+ format for CarbonData?</h2>
+<p>Edit carbon.properties file. Modify the value of parameter
+ <strong>carbon.data.file.version</strong>.<br>
+ Setting the parameter <strong>carbon.data.file.version</strong> to <code>1</code> will support
+ data loading in <code>old format(0.x version)</code> and setting <strong>carbon.data.file.version</strong>
+ to <code>2</code> will support data loading in <code>new format(1.x onwards)</code> only.<br>
+ By default the data loading is supported using the new format.</p>
+
+<h2 id="how-to-resolve-store-location-can-not-be-found">How to resolve store location can not be
+ found?</h2>
+<p>Try creating <code>carbonsession</code> with <code>storepath</code> specified in the following
+ manner :</p>
+<pre><code>val carbon = SparkSession.builder().config(sc.getConf).getOrCreateCarbonSession(<store_path>)
+</code></pre>
+<p>Example:</p>
+<pre><code>val carbon = SparkSession.builder().config(sc.getConf).getOrCreateCarbonSession("hdfs://localhost:9000/carbon/store ")
+</code></pre>
+
+<h2 id="what-is-carbon-lockt-ype">What is carbon.lock.type?</h2>
+<p>This property configuration specifies the type of lock to be acquired during concurrent
+ operations on table. This property can be set with the following values :</p>
+<ul>
+ <li><strong>LOCALLOCK</strong> : This Lock is created on local file system as file. This lock is
+ useful when only one spark driver (thrift server) runs on a machine and no other CarbonData
+ spark application is launched concurrently.
+ </li>
+ <li><strong>HDFSLOCK</strong> : This Lock is created on HDFS file system as file. This lock is
+ useful when multiple CarbonData spark applications are launched and no ZooKeeper is running
+ on cluster and the HDFS supports, file based locking.
+ </li>
+</ul>
+
+<h2 id="how-to-enable-auto-compaction">How to enable Auto Compaction?</h2>
+<p>To enable compaction set <strong>carbon.enable.auto.load.merge</strong> to <code>TRUE</code> in
+ the carbon.properties file.</p>
+
+<h2 id="how-to-resolve-abstract-method-error">How to resolve Abstract Method Error?</h2>
+<p>You need to specify the <code>spark version</code> while using Maven to build project.</p>
+
+<h2 id="getting-exception-on-creating-a-view">Getting Exception on Creating a View</h2>
+<p>View not supported in CarbonData.</p>
+
+<h2 id="is-carbondata-supported-for-windows">Is CarbonData supported for Windows?</h2>
+<p>We may provide support for windows in future. You are welcome to contribute if you want to add
+ the support :)</p>

-* **Getting Abstract method error**
+## Can we preserve Segments from Compaction?
+If you want to preserve number of segments from being compacted then you can set the property **carbon.numberof.preserve.segments** equal to the **value of number of segments to be preserved**.
- You need to specify the spark version while using Maven to build project.
+Note : *No segments are preserved by Default.*
-* **Getting NotImplementedException for subquery using IN and EXISTS**
+## Can we disable horizontal compaction?
+Yes, to disable horizontal compaction, set **carbon.horizontal.compaction.enable** to ``FALSE`` in carbon.properties file.
- Subquery with in and exists not supported in CarbonData.
-
-* **Getting Exceptions on creating a view**
-
- View not supported in CarbonData.
-
-* **How to verify if ColumnGroups have been created as desired.**
+## What is horizontal compaction?
+Compaction performed after Update and Delete operations is referred as Horizontal Compaction. After every DELETE and UPDATE operation, horizontal compaction may occur in case the delta (DELETE/ UPDATE) files becomes more than specified threshold.
- Try using desc table query.
-
-* **Did anyone try to run CarbonData on windows? Is it supported on Windows?**
-
- We may provide support for windows in future. You are welcome to contribute if you want to add the support :)
+By default the parameter **carbon.horizontal.compaction.enable** enabling the horizontal compaction is set to ``TRUE``.
-* **Can we execute Concurrent Operations(Load,Insert,Update) on table by multiple workers.**
-
- Concurrency is not supported in current release of CarbonData.
-
+## How to enable Compaction while data loading?
+To enable compaction while data loading, set **carbon.enable.auto.load.merge** to ``TRUE`` in carbon.properties file.
+
+## Where are Bad Records Stored in CarbonData?
+The bad records are stored at the location set in carbon.badRecords.location in carbon.properties file.
+By default **carbon.badRecords.location** specifies the following location ``/opt/Carbon/Spark/badrecords``.
+
+## What are Bad Records?
+Records that fail to get loaded into the CarbonData due to data type incompatibility are classified as Bad Records.
+
+## Can we use CarbonData on Standalone Spark Cluster?
+Yes, CarbonData can be used on a Standalone spark cluster. But using a standalone cluster has following limitations:
+- single node cluster cannot be scaled up
+- the maximum memory and the CPU computation power has a fixed limit
+- the number of processors are limited in a single node cluster
+
+To harness the actual speed of execution of CarbonData on petabytes of data, it is suggested to use a Multinode Cluster.
+
+## What versions of Apache Spark are Compatible with CarbonData?
+Currently **Spark 1.6.2** and **Spark 2.1** is compatible with CarbonData.
+
+## Can we Load Data from excel?
+Yes, the data can be loaded from excel provided the data is in CSV format.
+
+## How to enable Single Pass Data Loading?
+You need to set **SINGLE_PASS** to ``True`` and append it to ``OPTIONS`` Section in the query as demonstrated in the Load Query below :
+```
+LOAD DATA local inpath '/opt/rawdata/data.csv' INTO table carbontable
+OPTIONS('DELIMITER'=',', 'QUOTECHAR'='"','FILEHEADER'='empno,empname,designation','USE_KETTLE'='FALSE')
+```
+Refer to [DML-operations-in-CarbonData](https://github.com/PallaviSingh1992/incubator-carbondata/blob/6b4dd5f3dea8c93839a94c2d2c80ab7a799cf209/docs/dml-operation-on-carbondata.md) for more details and example.
+
+## What is Single Pass Data Loading?
+Single Pass Loading enables single job to finish data loading with dictionary generation on the fly. It enhances performance in the scenarios where the subsequent data loading after initial load involves fewer incremental updates on the dictionary.
+This option specifies whether to use single pass for loading data or not. By default this option is set to ``FALSE``.
+
+## How to specify the data loading format for CarbonData?
+Edit carbon.properties file. Modify the value of parameter **carbon.data.file.version**.
+Setting the parameter **carbon.data.file.version** to ``1`` will support data loading in ``old format(0.x version)`` and setting **carbon.data.file.version** to ``2`` will support data loading in ``new format(1.x onwards)`` only.
+By default the data loading is supported using the new format.
+
+## How to resolve store location can not be found?
+Try creating ``carbonsession`` with ``storepath`` specified in the following manner :
+```
+val carbon = SparkSession.builder().config(sc.getConf).getOrCreateCarbonSession(<store_path>)
+```
+Example:
+```
+val carbon = SparkSession.builder().config(sc.getConf).getOrCreateCarbonSession("hdfs://localhost:9000/carbon/store ")
+```
+
+## What is carbon.lock.type?
+This property configuration specifies the type of lock to be acquired during concurrent operations on table. This property can be set with the following values :
+- **LOCALLOCK** : This Lock is created on local file system as file. This lock is useful when only one spark driver (thrift server) runs on a machine and no other CarbonData spark application is launched concurrently.
+- **HDFSLOCK** : This Lock is created on HDFS file system as file. This lock is useful when multiple CarbonData spark applications are launched and no ZooKeeper is running on cluster and the HDFS supports, file based locking.
+
+## How to enable Auto Compaction?
+To enable compaction set **carbon.enable.auto.load.merge** to ``TRUE`` in the carbon.properties file.
+
+## How to resolve Abstract Method Error?
+You need to specify the ``spark version`` while using Maven to build project.
+
+## Getting Exception on Creating a View
+View not supported in CarbonData.
+
