Yu Li commented on HBASE-16960:
-------------------------------
One possible solution: invoking {{cleanupOutstandingSyncsOnException}} when
append failed with exception, it will cleanup existing sync requests recorded
in {{syncFutures}} but not offered to {{SyncRunner}} yet, so there won't be any
sync future left over if no further truck published to disruptor. Thoughts?
