Siddharth Seth commented on YARN-33:
------------------------------------

bq. I think we already do that right now. We have functions which removes the unhealthy log dirs and local dirs from the list. I followed the same model. I think its reasonable for the log/local dirs because people may have added multiple but if one of them is good we should be able to make cluster functioning and with the error message in the log that following disks are in bad shape.
These dirs are removed directly from the initial list (as against the initial list containing all configured dirs). They don't count towards bad disks, and the node health calculation.
