Subject [jira] [Commented] (HDFS-5242) Reduce contention on DatanodeInfo instances
Date Wed, 11 Dec 2013 19:45:08 GMT

Kihwal Lee commented on HDFS-5242:
----------------------------------

+1 for the patch.  However, the contention might have seen unusually high if only a small
number of data nodes were involved.
