-------------------------------------------

             Summary: [branch-1] Backport improvements to FSHLog from branch-2
                 Key: HBASE-25808
                 URL: https://issues.apache.org/jira/browse/HBASE-25808
             Project: HBase
          Issue Type: New Feature
          Components: regionserver, wal
    Affects Versions: 1.6.0
            Reporter: Andrew Kyle Purtell
            Assignee: Andrew Kyle Purtell
             Fix For: 1.7.0


From c96b642f15d (HBASE-15265 Implement an asynchronous FSHLog)
    - Better formatting; use { } instead of dangling ifs, elses, etc. in RingBufferEventHandler.
    
    From b1269ec57ff (HBASE-19811 Fix findbugs and error-prone warnings in hbase-server (branch-2))
    - Change syncFuturesCount in RingBufferEventHandler from 'volatile int' to AtomicInteger.
      'volatile' is insufficient for multithreaded access.
    
    From afc1746757f (HBASE-24034 [Flakey Tests] A couple of fixes and cleanups)
    - Make a local copy of takeSyncFuture after we get it in SyncRunner#run.
      This looks like a workaround for a JIT/compiler bug in some Java versions. (SCARY)
