[GitHub] [hbase] bharathv opened a new pull request #3400: HBASE-25998: Redo synchronization in SyncFuture

bharathv opened a new pull request #3400:
URL: https://github.com/apache/hbase/pull/3400


   Currently uses coarse grained synchronized approach that seems to
   create a lot of contention. This patch
   
   - Uses a reentrant lock instead of synchronized monitor
   - Switches to a condition variable based waiting rather than busy wait
   - Removed synchronization for unnecessary fields
