> Project: HBase
> Issue Type: Bug
> Components: Filters
> Affects Versions: 0.90.4
> Reporter: Cosmin Lehene
> Assignee: Todd Lipcon
> Priority: Blocker
> Fix For: 0.96.0

> 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.
