Hdfs Not Respond


Dear all,


On my hdfs instance I continue to find this error

ERROR org.apache.hadoop.hdfs.server.datanode.DataNode: error processing READ_BLOCK operation  src: / dst: / Replica gen stamp < block genstamp, block=BP-443384405-, 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
