Subject [jira] [Commented] (HDFS-10731) FSDirectory#verifyMaxDirItems does not log path name
Date Thu, 11 Aug 2016 21:04:20 GMT

    [ https://issues.apache.org/jira/browse/HDFS-10731?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15417938#comment-15417938

Xiao Chen commented on HDFS-10731:

This changes the constructor of the exception, but since the class is marked as {{Private}}
and {{Evolving}}, we should be good. Agree with assessment on test failures too.
+1, thanks Wei-Chiu.

The directory item limit of null is exceeded: limit=1048576 items=1048576

> The error message above logs the path name incorrectly (null). Without the path name
it is hard to tell which directory is in trouble. The exception should set the path name before
being logged.
> This bug was seen on a CDH 5.5.2 cluster, but CDH5.5.2 is roughly up to date with Apache
Hadoop 2.7.2.
