Subject [jira] [Commented] (HDFS-2863) Failures observed if dfs.edits.dir and shared.edits.dir have same directories.
Date Thu, 02 Feb 2012 22:50:56 GMT

    [ https://issues.apache.org/jira/browse/HDFS-2863?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13199316#comment-13199316

Bikas Saha commented on HDFS-2863:
----------------------------------

I did not assign editDirs = uniqueEditDirs because I did not want the Set semantics to leak
into the Collection return type of that method.
These are small lists anyways and so I wasnt bothered about the perf.

I will look at the other suggestions starting with finding out what a Joiner is :P

> If same edits directory is configured in twice, both are treated independently. Edit
log roll is called on the same directory twice causing exceptions.
