Concurrent flushers in HLog sync using HDFS-895

    Details

    • Hadoop Flags:
      Reviewed

      Description

      HDFS-895 changes hflush() to be able to run concurrently from multiple threads, where flushes can be concurrent with further writes to the same file.

      We need to rip out/amend the group commit code a bit to take advantage of this.
