Re: Hadoop NON DFS space

Hi Vikas,

You might want to check your logs. MR can generate huge logs depending
on what you are logging, and they are not on the DFS. The are on
non-dfs. If it's comming from there, you can change the loglevel to
reduce the size of the output.

On my own cluster, I turned the logs to debug and forgot to remove
that. At the end I ran into disks space issues because of that.
