-------------------------------
Attachment: HBASE-4987.D675.3.patch
khemani updated the revision "HBASE-4987 [jira] wrong use of incarnation var in
SplitLogManager".
Reviewers: tedyu, nspiegelberg, dhruba, JIRA
narrowed the synchronization block
This fixes of two issues
1. double counting of batch.installed is fixed. This is a simple fix. If the
new Task(batch) is not used then decrement batch.installed--. No lock is
requited to decrement batch.installed. Only one thread ever looks at this value.
2. There was an unhandled race between the zookeeper-callback thread calling
setDone() on a task not part of any batch and another thread incorporating that
task into a batch. That is now fixed.
