Subject [jira] [Commented] (HDFS-8664) Allow wildcards in dfs.datanode.data.dir
Date Wed, 01 Jul 2015 02:30:05 GMT

    [ https://issues.apache.org/jira/browse/HDFS-8664?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14609467#comment-14609467

Patrick White commented on HDFS-8664:
-------------------------------------

Somethings messed up and I've lost the will to live for the day. After many hundreds of runs
without change, it eventually ran fine. So I'm mentally marking this as a flaky test and I'll
pick back up tomorrow.

> We have many disks per machine (12+) that don't always have the same numbering when they
come back from provisioning, but they're always in the same tree following the same pattern.
> It would greatly reduce our config complexity to be able to specify a wildcard for all
the data directories.
