ryan rawson commented on HBASE-2645: ------------------------------------ Dhruba can you please commit the proper patch to 0.20-append so we can close this issue? In the mean time we'll move it to 0.92 since many people are running cdh3b2. > HLog writer can do 1-2 sync operations after lease has been recovered for > split process. > ---------------------------------------------------------------------------------------- > > Key: HBASE-2645 > URL: https://issues.apache.org/jira/browse/HBASE-2645 > Project: HBase > Issue Type: Bug > Components: io > Affects Versions: 0.92.0 > Reporter: Cosmin Lehene > Assignee: Todd Lipcon > Priority: Blocker > Fix For: 0.90.0 > > > TestHLogSplit.testLogCannotBeWrittenOnceParsed is failing. > This test starts a thread that writes one edit to the log, syncs and counts. > During this, a HLog.splitLog operation is started. splitLog recovers the log > lease before reading the log, so that the original regionserver could not > wake up and write after the split process started. > The test compares the number of edits reported by the split process and by > the writer thread. Writer thread (called zombie in the test) should report <= > than the splitLog (sync() might raise after the last edit gets written and > the edit won't get counted by zombie thread). However it appears that the > zombie counts 1-2 more edits. So it looks like it can sync without a lease. > This might be a hdfs-0.20 related issue. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
