I/O error constructing remote block reader.


I am getting a lot of I/O error constructing remote block reader. When performing batch file uploads to HBase Got error for OP_READ_BLOCK, self=/, remote=/, for file /user/hbase/.staging/job_1407795783485_1084/libjars/hbase-server-0.98.1-cdh5.1.0.jar, for pool BP-504567843- block 1075088397_1099513328611 at org.apache.hadoop.hdfs.RemoteBlockReader2.checkSuccess( at org.apache.hadoop.hdfs.RemoteBlockReader2.newBlockReader( at org.apache.hadoop.hdfs.BlockReaderFactory.getRemoteBlockReader( error processing READ_BLOCK operation src: / dest: / org.apache.hadoop.hdfs.server.datanode.ReplicaNotFoundException: Replica not found for BP-504567843- at org.apache.hadoop.hdfs.server.datanode.BlockSender.getReplica( at org.apache.hadoop.hdfs.server.datanode.BlockSender.( at org.apache.hadoop.hdfs.server.datanode.DataXceiver.readBlock( at org.apache.hadoop.hdfs.protocol.datatransfer.Receiver.opReadBlock( at org.apache.hadoop.hdfs.protocol.datatransfer.Receiver.processOp( at at

I don't seem to be getting errors during the app processing itself, so I am not sure if this is a problem to worry about, but I would like to know what is causing this so that I may keep my eyes peeled
