Directory /tmp/hadoop-hadoop/dfs/name is in an inconsistent state: storage directory does not exist

[Pankil Doshi]

Hello Everyone,

At time I get following error,when i restart my cluster desktops.(Before
that I shutdown mapred and dfs properly though).
Temp folder contains of the directory its looking for.Still I get this
error.
Only solution I found to get rid with this error is I have to format my dfs
entirely and then load the data again. and start whole process.

But in that I loose my data on HDFS and I have to reload it.

Does anyone has any clue abt it?
