Subject [jira] [Commented] (HDFS-4657) If incremental BR is received before first full BR NN will log a line for every block on a DN
Date Fri, 05 Apr 2013 19:57:16 GMT

    [ https://issues.apache.org/jira/browse/HDFS-4657?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13624004#comment-13624004

Todd Lipcon commented on HDFS-4657:
-----------------------------------

I agree something like #3 makes sense. Let's just put a limit on the number of blocks logged
in any BR (something like 1000 or even 10000).

> This can impact restart times pretty substantially if the DNs have a lot of blocks, and
since the FSNS write lock is held while processing the block report clients will not make
any progress.
