Subject [jira] [Created] (HBASE-14411) Fix UT failures when using multiwal as default provider
Date Fri, 11 Sep 2015 18:58:45 GMT
Yu Li created HBASE-14411:
-----------------------------

             Summary: Fix UT failures when using multiwal as default provider
                 Key: HBASE-14411
                 URL: https://issues.apache.org/jira/browse/HBASE-14411
             Project: HBase
          Issue Type: Bug
            Reporter: Yu Li
            Assignee: Yu Li
             Fix For: 2.0.0


If we set hbase.wal.provider to multiwal in hbase-server/src/test/resources/hbase-site.xml
which allows us to use BoundedRegionGroupingProvider in UT, we will observe below failures
in current code base:

While patch for HBASE-14306 could resolve failures of TestHLogRecordReader, TestReplicationSourceManager
and TestReplicationWALReaderManager, this JIRA will focus of resolving the others
