Subject [jira] [Commented] (MAPREDUCE-2644) NodeManager fails to create containers when NM_LOG_DIR is not explicitly set in the Configuration
Date Wed, 06 Jul 2011 01:52:16 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-2644?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13060233#comment-13060233
] 

Aaron T. Myers commented on MAPREDUCE-2644:
-------------------------------------------

Hey Josh, the usual thing done in the rest of the Hadoop code when providing a default value
for a config is to use the two-argument version of {{Configuration.get(...)}} whose first
argument is the config key and whose second argument will be returned as the value if no value
for that key is set in the conf object.

> If the yarn configuration does not explicitly specify a value for the yarn.server.nodemanager.log.dir
property, container allocation will fail on the NodeManager w/an NPE when the LocalDirAllocator
goes to create the temp directory. In most of the code, we handle this by defaulting to /tmp/logs,
but we cannot do this in the LocalDirAllocator context, so we need to set the default value
explicitly in the Configuration.
> Marking this as major b/c it's annoying to bump into it when you're getting your first
MRv2 cluster up and running. :)
