Subject [jira] [Updated] (HDFS-8664) Allow wildcards in dfs.datanode.data.dir
Date Mon, 29 Jun 2015 20:03:05 GMT

     [ https://issues.apache.org/jira/browse/HDFS-8664?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Patrick White updated HDFS-8664:
--------------------------------
    Attachment: HDFS-8664.002.patch

Think I got the test failures in line. Ran as many tests as I could (was getting entirely
unrelated failures, so not super confident, but HDFS stuff passed).

The 2.7 version of this cherry-pick is giving some very interesting problems than I'm digging
into. Looks like it's trying to load block pools multiple times and failing.

> 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.
