Andrew Purtell commented on HBASE-2087: --------------------------------------- bq. Should we open a blanket issue in which we discuss undoing "compensating" changes now hdfs has a working sync +1 Like we did with the compaction limiting thread and region server "safe mode" after the transition to 0.20. > The wait on compaction because "Too many store files" holds up all flushing > --------------------------------------------------------------------------- > > Key: HBASE-2087 > URL: https://issues.apache.org/jira/browse/HBASE-2087 > Project: Hadoop HBase > Issue Type: Bug > Reporter: stack > > The method MemStoreFlusher#checkStoreFileCount is called from flushRegion. > flushRegion is called by MemStoreFlusher#run thread. If the > checkStoreFileCount finds too many store files, it'll stick around waiting on > a compaction to happen. While its hanging, the MemStoreFlusher#run is held > up. No other region can flush. Meantime WALs will be rolling and memory > will be accumulating writes. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
