[GitHub] [hbase] comnetwork commented on pull request #4721: HBASE-27231 FSHLog should retry writing WAL entries when syncs to HDF…

   @Apache9 ，thank you very much for point this out, yes, the original {{FSHLog.RingBufferEventHandler.onEvent}} which called {{FSHLog.append}}  also have the same problem you described and may also block the single-thread,  this is the problem of the {{FSOutputStream}} itself. Here I just want to make {{FSHLog}} could retry as {{AsyncFSWAL}} when possible, in the PR , if {{FSHlog.append}} throws exception, we could also reuse the logic in {{AsyncFSWAL.syncFailed}} to retry.
