Subject [jira] [Commented] (HDFS-9214) Support reconfiguring dfs.datanode.balance.max.concurrent.moves without DN restart
Date Fri, 04 Dec 2015 23:30:11 GMT

    [ https://issues.apache.org/jira/browse/HDFS-9214?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15042413#comment-15042413
] 

Chris Nauroth commented on HDFS-9214:
-------------------------------------

There is a license warning on the new {{TestDataNodeReconfiguration}} class.  Would you mind
adding the license header there?

The warning was easy to miss, because we currently have a problem with tests writing files
outside the Maven target directory, which then get flagged for license violations.  {{TestDataNodeReconfiguration}}
was at the bottom of the list.

HDFS-9263 tracks the effort to fix that.
