[jira] [Updated] (WHIRR-351) configure_hadoop should create+chown
all data dirs listed in hadoop-hdfs.dfs.data.dir
[ https://issues.apache.org/jira/browse/WHIRR-351?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Karel Vervaeke updated WHIRR-351:
---------------------------------
Attachment: WHIRR-351.patch
Updated patch chowns the mapred local dir to mapred:mapred instead of root:root
(TaskTracker doesn't like it if ownership isn't right, even if permissions are ok)

> To avoid the problem, the directories should be created before starting the datanodes.
