Hdfs Not Respond

Explorer

Dear all,

 

On my hdfs instance I continue to find this error

ERROR org.apache.hadoop.hdfs.server.datanode.DataNode: ip-10-0-11-18.eu-west-1.compute.internal:50010:DataXceiver error processing READ_BLOCK operation  src: /10.0.11.18:48672 dst: /10.0.11.18:50010

java.io.IOException: Replica gen stamp < block genstamp, block=BP-443384405-10.0.11.18-1425373333474:blk_1146735050_73143271, replica=ReplicaWaitingToBeRecovered, blk_1146735050_0, RWR

 

In this forum or other the only description is to check the network configuration. There is no iptables enabled and there is not other firewall.

It's really a problem because every 7-8 hour the system goes down 

 

Can anyone help me?

 

Thanks in advance
