Subject [jira] [Commented] (HDFS-10645) Make block report size as a metric and add this metric to datanode web ui
Date Thu, 18 Aug 2016 02:48:20 GMT

    [ https://issues.apache.org/jira/browse/HDFS-10645?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15425827#comment-15425827

Yuanbo Liu commented on HDFS-10645:
-----------------------------------

[~ajisakaa] Thanks for your review.
I've tested the failures {{TestBootstrapStandby}} and {{TestCrcCorruption}} in my local environment
and they all pass.
So I think those test failures are not related to my change.
Thanks again for your time.

> Record block report size as a metric and show it on datanode UI. It's important for administrators
to know the bottleneck of  block report, and the metric is also a good tuning metric.
