Hi Users,
In my cluster setup i am doing one test case of making only all
datanodes down and keep namenode running.
In this case my application gets error with remoteException:
could only be replicated to 0 nodes instead of minReplication (=1).
There are 0 datanode(s) running and no node(s) are excluded in this
operation
Then i make all datanodes up, but i still faces above exception looks
like datanode came up but not sync with namenode.
I have to then restart my application for writing files to hdfs. After
restart it starts processing fine but i don't want to kill my
application in this case.
Prompt help is highly appreciated!!
Regards,
Satyam
