-------------------------------------------
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)
