Subject [jira] [Commented] (HBASE-9255) TestAsyncProcess#testErrorsServers is flaky on suse linux
Date Sat, 17 Aug 2013 02:01:48 GMT

    [ https://issues.apache.org/jira/browse/HBASE-9255?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13742793#comment-13742793
] 

Jeffrey Zhong commented on HBASE-9255:
--------------------------------------

[~tedyu@apache.org] Because {code} HTable ht = new HTable();{code} doesn't set writeBufferSize.
The fix is to add the line {code}ht.setWriteBufferSize{code}. to set writeBufferSize otherwise
its value is 0. The default you mentioned is only for default config value while the above
case is that we don't even use the config "hbase.client.write.buffer" at all. Thanks.

> TestAsyncProcess#testErrorsServers fails quite frequently on Suse because HTable.WriteBufferSize
is NOT set so the test may fail at HTable.put command where backgroundFlushCommits kicks in.
