Steve Loughran updated HDFS-884: -------------------------------- Fix Version/s: 0.22.0 Status: Patch Available (was: Open) > DataNode makeInstance should report the directory list when failing to start > up > ------------------------------------------------------------------------------- > > Key: HDFS-884 > URL: https://issues.apache.org/jira/browse/HDFS-884 > Project: Hadoop HDFS > Issue Type: Improvement > Components: data-node > Affects Versions: 0.22.0 > Reporter: Steve Loughran > Assignee: Steve Loughran > Priority: Minor > Fix For: 0.22.0 > > Attachments: HDFS-884.patch > > > 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. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
