Subject [jira] Commented: (HDFS-884) DataNode makeInstance should report the directory list when failing to start up
Date Sat, 09 Jan 2010 21:37:54 GMT

    [ https://issues.apache.org/jira/browse/HDFS-884?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12798408#action_12798408
] 

Steve Loughran commented on HDFS-884:
-------------------------------------

HDFS-890 would extend and obsolete this issue/patch, as instead of reporting problems, makeInstance
should raise an exception listing all failing directories and the reasons, and at least one
nested cause.

> When {{Datanode.makeInstance()}} cannot work with one of the directories in dfs.data.dir,
it logs this at warn level (while losing the stack trace). 
> It should include the nested exception for better troubleshooting. Then, when all dirs
in the list fail, an exception is thrown, but this exception does not include the list of
directories. It should list the absolute path of every missing/failing directory, so that
whoever sees the exception can see where to start looking for problems: either the filesystem
or the configuration.
