Subject [jira] [Commented] (HDFS-7408) Add a counter in the log that shows the number of block reports processed
Date Tue, 18 Nov 2014 22:37:34 GMT

    [ https://issues.apache.org/jira/browse/HDFS-7408?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14216949#comment-14216949

Aaron T. Myers commented on HDFS-7408:
--------------------------------------

Hey Suresh, are you envisioning this printing just a counter for the total number of block
reports processed? Or total number of BRs (full and incremental?) for each DN? Or perhaps
even breaking it down per individual storage, instead of per DN? Also, if we're going to put
this in the logs, let's make sure it also shows up in JMX output as well.

> It would be great to have in the info log corresponding to block report processing, printing
information on how many block reports have been processed. This can be useful to debug when
namenode is unresponsive especially during startup time to understand if datanodes are sending
block reports multiple times.
