+ Apache Kylin is an effort undergoing incubation at The Apache Software Foundation (ASF), sponsored by the Apache Incubator. Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making process have stabilized in a manner consistent with other successful ASF projects. While incubation status is not necessarily a reflection of the completeness or stability of the code, it does indicate that the project has yet to be fully endorsed by the ASF.

+ Apache Kylin is an effort undergoing incubation at The Apache Software Foundation (ASF), sponsored by the Apache Incubator. Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making process have stabilized in a manner consistent with other successful ASF projects. While incubation status is not necessarily a reflection of the completeness or stability of the code, it does indicate that the project has yet to be fully endorsed by the ASF.

+<p>1) When you build the cube and get this error: java.net.ConnectException: to 0.0.0.0:10020 failed on connection exception, you can try to change this file.</p>
+
+<p>config ${hadoop install}/etc/hadoop/mapred-site.xml, and add this code:</p>

+ <name>mapreduce.jobhistory.address</name>
+ <value>host:10020</value>

+
+<p>Execute this cmd after the configuration:
+$ mr-jobhistory-daemon.sh start historyserver</p>
+
+<p>2) The version of hadoop which Hbase used must be same as the hadoop cluster.</p>
+
+<p>For example:</p>
+
+<p>In Hbase0.98.0-hadoop2 use hadoop 2.2.0, if your hadoop cluster is 2.4.1, then you need to replace all the hadoop jars from 2.2.0 to 2.4.1.</p>

+ Apache Kylin is an effort undergoing incubation at The Apache Software Foundation (ASF), sponsored by the Apache Incubator. Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making process have stabilized in a manner consistent with other successful ASF projects. While incubation status is not necessarily a reflection of the completeness or stability of the code, it does indicate that the project has yet to be fully endorsed by the ASF.

+
+ <article class="post-content" >
+ <p>Kylin is doing a round code refactor which will introduce the following two changes on meta data:</p>
+
+<ul>
+ <li>Abstract a âmodel_descâ layer from âcube_descâ</li>
+</ul>
+
+<p>Before define a cube, user will need firstly define a model (âmodel_descâ); The model defines which is the fact table, which are lookup tables and how they be joined;</p>
+
+<p>With the model be defined, when user define a cube (âcube_descâ), he/she only need to specify the table/column name for a dimension, as the join conditions have already been defined;</p>
+
+<p>This abstraction is to extend the meta data to fulfill non-cube queries (coming soon);</p>
+
+<ul>
+ <li>Support data tables from multiple hive databases;</li>
+</ul>
+
+<p>User has the case that tables are from multiple hive database, and the table name might be the same; To support this case Kylin will use the database name + table name as the unique name for tables; And user need to specify the database name (if it is not âdefaultâ) in SQL when query Kylin. </p>
+
+<p>Here is a sample; the fact table âtest_kylin_factâ is from default hive database, you donât need to specify the db name; while lookup table is from âedwâ, you need use âedw.test_cal_dtâ in the query:</p>
+
+<div class="highlight"><pre><code class="language-groff" data-lang="groff">select test_cal_dt.Week_Beg_Dt, sum(price) as c1, count(1) as c2
+ from test_kylin_fact
+ inner JOIN edw.test_cal_dt as test_cal_dt
+ ON test_kylin_fact.cal_dt = test_cal_dt.cal_dt
+ where test_kylin_fact.lstg_format_name='ABIN'</code></pre></div>

+ Apache Kylin is an effort undergoing incubation at The Apache Software Foundation (ASF), sponsored by the Apache Incubator. Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making process have stabilized in a manner consistent with other successful ASF projects. While incubation status is not necessarily a reflection of the completeness or stability of the code, it does indicate that the project has yet to be fully endorsed by the ASF.
