Subject When all datanodes get down and namenode is still up
Date Thu, 31 Jul 2014 10:11:11 GMT
Hello Users,


When i made all datnodes down and namenode is still up writing failures 
occures which is fine.
But after few mins i have made all datanode up one by one.
But still i observe writing failures and it looks like datanodes are not 
available.

This state resolves only when i restart my application and hadoop 
cluster restart with format.And this is what i don't want to do.

If anyone face this type of issue then please suggest what to do.


Regards,
Satyam
