Hi Guys,
I have 4datanodes and one master node EMR cluster with 120GB data storage
left. I have been running sqoop jobs which loads data to hive table. After
some jobs ran successfully I suddenly see these errors all over the name
node logs and datanodes logs.
I have tried changing so many configurations as suggeted in stackoverflow
and hortonworks sites but couldnt find a way for fixing it.
Here is the error:
2018-06-12 15:32:35,933 WARN [main] org.apache.hadoop.mapred.YarnChild:
Exception running child :

could only be replicated to 0 nodes instead of minReplication (=1). There
are 4 datanode(s) running and no node(s) are excluded in this operation.
