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
