HDFS Datanode failure

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!

Re: HDFS Datanode failure

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