chunhui shen updated HBASE-7507: -------------------------------- Description: We will abort regionserver if memstore flush throws exception. I thinks we could do retry to make regionserver more stable because file system may be not ok in a transient time. e.g. Switching namenode in the NamenodeHA environment {code} HRegion#internalFlushcache(){ ... try { ... }catch(Throwable t){ DroppedSnapshotException dse = new DroppedSnapshotException("region: " + Bytes.toStringBinary(getRegionName())); dse.initCause(t); throw dse; } ... } MemStoreFlusher#flushRegion(){ ... region.flushcache(); ... try { }catch(DroppedSnapshotException ex){ server.abort("Replay of HLog required. Forcing server shutdown", ex); } ... } {code} was: We will abort regionserver if memstore flush throws exception.
