[jira] [Created] (HDFS-14141) Enable GC monitoring thread for OIV tool

Siyao Meng created HDFS-14141:
---------------------------------

             Summary: Enable GC monitoring thread for OIV tool
                 Key: HDFS-14141
                 URL: https://issues.apache.org/jira/browse/HDFS-14141
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: hdfs
    Affects Versions: 3.0.0
            Reporter: Siyao Meng


It took OIV quite a long time (84 minutes) to dump a 14G FSImage. I suspect there was a lot of GC going on. I think we could add an option like '-m,--gc-monitor' to enable GC monitoring thread for OIV tool.
