When all datanodes get down and namenode is still up
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
