Cannot find row in .META. for table

Hi,
I am using Hbase 0.94.1 with Hadoop 1.2.1 and using Thrift API to access tables stored in Hbase from my C# application. I am able to connect to Server but while going to perform any operation from client it gives following error in CLI-log:

14/03/11 12:18:53 WARN client.HConnectionManager$HConnectionImplementation: Encountered problems when prefetch META table:

But I can access my table from Hbase Shell with all shell operations. I am totally stuck here, please devise some methods to overcome this issue.

Re: Cannot find row in .META. for table

Posted by Ted Yu <yu...@gmail.com>.
I don't see thrift-specific parameters in the list below.
Please take a look at:
  http://hbase.apache.org/book.html#hbase_default_configurations
starting with hbase.thrift.minWorkerThreads

If you have the luxury of trying out Java client, you would be able to tell
whether the slowness was specific to thrift.

In your first email, you mentioned 0.94.1 - please consider upgrading to
0.94.17, there have been ton of improvements since 0.94.1

Now that you're able to connect, I suggest wrapping up this thread.
Feel free to ask thrift performance questions under a different subject.

Cheers

RE: Cannot find row in .META. for table

Hi Ted,
Thanks for the help. Now I am able to scan Hbase tables with Thrift API but I am getting 1015 rows in 4 seconds.

By Any means can I get better performance from Thrift? Please Advise.

Adding back user@

Can you look at the example in this post and compose startRow accordingly ?

Hi Ted,
By giving null to attributes, scanner is working now, thanks for the idea.
But, when I give Guid.Empty.ToByteArray() as ByteBuffer startRow parametes's value, I am getting no rows in scannerGet_result.
Please let me know what value should I pass for start row parameter.

Have you seen this ?

Looking at src/main/java/org/apache/hadoop/hbase/thrift/ThriftServerRunner.java :

  private static void addAttributes(OperationWithAttributes op,
    Map<ByteBuffer, ByteBuffer> attributes) {
    if (attributes == null || attributes.size() == 0) {
      return;

You can pass C# equivalent of null for attributes.

Cheers

Thanks for the reply Ted. I am using Hbase-sharp dll which is portd with kind-of old scannerOpen() method which has no Map<ByteBuffer,ByteBuffer> attributes parameter.
I have also generated c# code from new Thrift server in which I am getting 4 arguments as you have listed.
Now , my concern is in what way I should give {ByteBuffer startRow} and {Map<ByteBuffer,ByteBuffer> attributes } parameter because I want to get all rows from the specified table.

In src/main//java/org/apache/hadoop/hbase/thrift/generated/Hbase.java , I found the following scannerOpen() methods:

    public int scannerOpen(ByteBuffer tableName, ByteBuffer startRow, List<ByteBuffer> columns, Map<ByteBuffer,ByteBuffer> attributes) throws IOError, org.apache.thrift.TException;
    public void scannerOpen(ByteBuffer tableName, ByteBuffer startRow, List<ByteBuffer> columns, Map<ByteBuffer,ByteBuffer> attributes, org.apache.thrift.async.AsyncMethodCallback<AsyncClient.scannerOpen_call>

resultHandler) throws org.apache.thrift.TException {

None of the above takes 3 parameters.

Adding back user@

Can you look at the example in this post and compose startRow accordingly ?

Hi Ted,
By giving null to attributes, scanner is working now, thanks for the idea.
But, when I give Guid.Empty.ToByteArray() as ByteBuffer startRow parametes's value, I am getting no rows in scannerGet_result.
Please let me know what value should I pass for start row parameter.

Have you seen this ?

http://stackoverflow.com/questions/10078348/byte-collection-based-similar-with-bytebuffer-from-java

Looking at src/main/java/org/apache/hadoop/hbase/thrift/ThriftServerRunner.java :

  private static void addAttributes(OperationWithAttributes op,
    Map<ByteBuffer, ByteBuffer> attributes) {
    if (attributes == null || attributes.size() == 0) {
      return;

You can pass C# equivalent of null for attributes.

Cheers

Thanks for the reply Ted. I am using Hbase-sharp dll which is portd with kind-of old scannerOpen() method which has no Map<ByteBuffer,ByteBuffer> attributes parameter.
I have also generated c# code from new Thrift server in which I am getting 4 arguments as you have listed.
Now , my concern is in what way I should give {ByteBuffer startRow} and {Map<ByteBuffer,ByteBuffer> attributes } parameter because I want to get all rows from the specified table.

In src/main//java/org/apache/hadoop/hbase/thrift/generated/Hbase.java , I found the following scannerOpen() methods:

    public int scannerOpen(ByteBuffer tableName, ByteBuffer startRow, List<ByteBuffer> columns, Map<ByteBuffer,ByteBuffer> attributes) throws IOError, org.apache.thrift.TException;
    public void scannerOpen(ByteBuffer tableName, ByteBuffer startRow, List<ByteBuffer> columns, Map<ByteBuffer,ByteBuffer> attributes, org.apache.thrift.async.AsyncMethodCallback<AsyncClient.scannerOpen_call>
resultHandler) throws org.apache.thrift.TException;
    public int scannerOpen(ByteBuffer tableName, ByteBuffer startRow, List<ByteBuffer> columns, Map<ByteBuffer,ByteBuffer> attributes) throws IOError, org.apache.thrift.TException
    public void scannerOpen(ByteBuffer tableName, ByteBuffer startRow, List<ByteBuffer> columns, Map<ByteBuffer,ByteBuffer> attributes, org.apache.thrift.async.AsyncMethodCallback<scannerOpen_call>
resultHandler) throws org.apache.thrift.TException {

None of the above takes 3 parameters.

Re: Cannot find row in .META. for table

Posted by Ted Yu <yu...@gmail.com>.
Looking at src/main/java/org/apache/hadoop/hbase/filter/ParseFilter.java :

    filterHashMap.put("SingleColumnValueFilter",
ParseConstants.FILTER_PACKAGE + "." +
                      "SingleColumnValueFilter");

SingleColumnValueFilter should be supported.

Can you show the complete stack trace ?

RE: Cannot find row in .META. for table

Posted by Umesh Chaudhary <um...@jci.com>.
Hi TED,
Now, I can successfully scan tables from Hbase but when I am using Filter like :

scanFilter.FilterString = GetBytesFromString("SingleColumnValueFilter(' ', 'COND_P', = , 'binary:0.0')"); { I have given <space> as Column family }

I an getting this error:
" java.lang.IllegalArgumentException: Filter Name SingleColumnValueFilter not supported", but I need SingleColumnValueFilter due to my requirement.

Please help that how can I use filters with scannerOpen?

Hi Ted,
By giving null to attributes, scanner is working now, thanks for the idea.
But, when I give Guid.Empty.ToByteArray() as ByteBuffer startRow parametes's value, I am getting no rows in scannerGet_result.
Please let me know what value should I pass for start row parameter.

Have you seen this ?

http://stackoverflow.com/questions/10078348/byte-collection-based-similar-with-bytebuffer-from-java

Looking at src/main/java/org/apache/hadoop/hbase/thrift/ThriftServerRunner.java :

  private static void addAttributes(OperationWithAttributes op,
    Map<ByteBuffer, ByteBuffer> attributes) {
    if (attributes == null || attributes.size() == 0) {
      return;

You can pass C# equivalent of null for attributes.

Cheers

Thanks for the reply Ted. I am using Hbase-sharp dll which is portd with kind-of old scannerOpen() method which has no Map<ByteBuffer,ByteBuffer> attributes parameter.
I have also generated c# code from new Thrift server in which I am getting 4 arguments as you have listed.
Now , my concern is in what way I should give {ByteBuffer startRow} and {Map<ByteBuffer,ByteBuffer> attributes } parameter because I want to get all rows from the specified table.

In src/main//java/org/apache/hadoop/hbase/thrift/generated/Hbase.java , I found the following scannerOpen() methods:

    public int scannerOpen(ByteBuffer tableName, ByteBuffer startRow, List<ByteBuffer> columns, Map<ByteBuffer,ByteBuffer> attributes) throws IOError, org.apache.thrift.TException;
    public void scannerOpen(ByteBuffer tableName, ByteBuffer startRow, List<ByteBuffer> columns, Map<ByteBuffer,ByteBuffer> attributes, org.apache.thrift.async.AsyncMethodCallback<AsyncClient.scannerOpen_call>
resultHandler) throws org.apache.thrift.TException;
    public int scannerOpen(ByteBuffer tableName, ByteBuffer startRow, List<ByteBuffer> columns, Map<ByteBuffer,ByteBuffer> attributes) throws IOError, org.apache.thrift.TException
    public void scannerOpen(ByteBuffer tableName, ByteBuffer startRow, List<ByteBuffer> columns, Map<ByteBuffer,ByteBuffer> attributes, org.apache.thrift.async.AsyncMethodCallback<scannerOpen_call>
resultHandler) throws org.apache.thrift.TException {

None of the above takes 3 parameters.

RE: Cannot find row in .META. for table

Posted by Umesh Chaudhary <um...@jci.com>.
Thanks for the reply Ted. I am using Hbase-sharp dll which is portd with kind-of old scannerOpen() method which has no Map<ByteBuffer,ByteBuffer> attributes parameter.
I have also generated c# code from new Thrift server in which I am getting 4 arguments as you have listed.
Now , my concern is in what way I should give {ByteBuffer startRow} and {Map<ByteBuffer,ByteBuffer> attributes } parameter because I want to get all rows from the specified table.

    public int scannerOpen(ByteBuffer tableName, ByteBuffer startRow, List<ByteBuffer> columns, Map<ByteBuffer,ByteBuffer> attributes) throws IOError, org.apache.thrift.TException;
    public void scannerOpen(ByteBuffer tableName, ByteBuffer startRow, List<ByteBuffer> columns, Map<ByteBuffer,ByteBuffer> attributes, org.apache.thrift.async.AsyncMethodCallback<AsyncClient.scannerOpen_call>

resultHandler) throws org.apache.thrift.TException {

None of the above takes 3 parameters.

RE: Cannot find row in .META. for table

Posted by Umesh Chaudhary <um...@jci.com>.
Please suggest the parameters for scannerOpen() merthod. 
As I am new to Thrift server API, Please guide me if I am passing parameters wrongly and because of that I am getting below error.

I am getting below message while running hbck with/without parameters:

If there are 0 inconsistencies then why I am facing this issue?
Please check my code:

var rows = _hbase.getRow(table_name, BitConverter.GetBytes("Asset"));---> where "Asset" is my column family.

OR

var scanner = _hbase.scannerOpen(table_name,BitConverter.GetBytes(1),columnsListinByteArray);

Because I am newbie to Thrift API for C#, please suggest how can I provide arguments for the same.

without any parameter to have a sense of what hbck will find.

Re: Cannot find row in .META. for table

Posted by divye sheth <di...@gmail.com>.
You can use the hbck utility to repair these kinds of problems.

$ hbase hbck -repair
OR
$ hbase hbck -fixMeta

Thanks
