Subject [jira] [Created] (HDFS-8867) Enable optimized block reports
Date Thu, 06 Aug 2015 20:57:04 GMT
Rushabh S Shah created HDFS-8867:
------------------------------------

             Summary: Enable optimized block reports
                 Key: HDFS-8867
                 URL: https://issues.apache.org/jira/browse/HDFS-8867
             Project: Hadoop HDFS
          Issue Type: Bug
    Affects Versions: 2.7.0
            Reporter: Rushabh S Shah
            Assignee: Daryn Sharp
             Fix For: 2.7.2


Opening this ticket on behalf of [~daryn]
HDFS-7435 introduced a more efficiently encoded block report format designed to improve performance
and reduce GC load on the NN and DNs. The NN is not advertising this capability to the DNs
so old-style reports are still being used.
