> HLog can be null when create table
> ----------------------------------
>
> Key: HBASE-6327
> URL: https://issues.apache.org/jira/browse/HBASE-6327
> Project: HBase
> Issue Type: Bug
> Reporter: ShiXing
> Assignee: ShiXing
> Fix For: 0.96.0, 0.94.4
>
> Attachments: 6327.txt, createTableFailedMaster.log,
> HBASE-6327-trunk-V1.patch
>
>
> As HBASE-4010 discussed, the HLog can be null.
> We have meet createTable failed because the no use hlog.
> When createHReagion, the HLog.LogSyncer is run sync(), in under layer it call
> the DFSClient.DFSOutputStream.sync().
> Then the hlog.closeAndDelete() was called，firstly the HLog.close() will
> interrupt the LogSyncer, and interrupt DFSClient.DFSOutputStream.sync().The
> DFSClient.DFSOutputStream will store the exception and throw it when we
> called DFSClient.close().
> The HLog.close() call the writer.close()/DFSClient.close() after interrupt
> the LogSyncer. And there is no catch exception for the close().
> So the Master throw exception to the client. There is no need to throw this
> exception, further， the hlog is no use.
> Our cluster is 0.90, the logs is attached, after "closing hlog writer", there
> is no log for the createTable().
> The trunk and 0.92, 0.94, we used just one hlog, and if the exception
> happends, the client will got createTable failed, but indeed ,we expect all
> the regions for the table can also be assigned.
> I will give the patch for this later.
