HDFS Datanode failure

HDFS Datanode failure

Explorer

Hello,

 

I have 3 instances of Solr in my cluster from which one is down. I tried to restart it several times with no success. The logs of the Solr instance are showing that the instance is trying to connect to a datanode:

 

 

2015-11-23 09:32:02,005 DEBUG org.apache.hadoop.hdfs.DFSClient: Connecting to datanode b1node11:50010
2015-11-23 09:32:02,005 DEBUG org.apache.hadoop.hdfs.DFSClient: Connecting to datanode b1node11:50010

On the HDFS side, the logs are showing there is an issue with the data node to which the Solr instance tries to connect.

ERROR org.apache.hadoop.hdfs.server.datanode.DataNode: b1node11:50010:DataXceiver error processing WRITE_BLOCK operation  src: /192.168.10.211:25048 dst: /192.168.10.211:50010

I restarted the datanode with no success.

Any help is appreciated!

Master Guru
What is the exact error you receive on the Solr side when it fails to come up? Could you please post the log?
