Subject [jira] [Commented] (HDFS-7875) Improve log message when wrong value configured for dfs.datanode.failed.volumes.tolerated
Date Sun, 22 Mar 2015 22:33:11 GMT

    [ https://issues.apache.org/jira/browse/HDFS-7875?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14375203#comment-14375203
] 

Harsh J commented on HDFS-7875:
-------------------------------

The new error looks better, but do you feel its possible to also print the # of currently
configured volumes, to add further context into the error?

Also two nits:

1. "configurd" -> "configured"
2. "Value configured is either 0" -> "Value configured is either less than 0" (0 is a valid
value)

> Improve log message when wrong value configured for dfs.datanode.failed.volumes.tolerated

> By mistake i configured dfs.datanode.failed.volumes.tolerated equal to the number of
volume configured. Got stuck for some time in debugging since the log message didn't give
much details.
> The log message can be more detail. Added a patch with change in message.
> Please have a look
