문제

I have 5 datanodes in my Cloudera cluster (CDH4) and all are showing as healthy.

The only service with an issue is HDFS which is showing under replication. When I go to host:50070/dfsnodelist.jsp?whatNodes=LIVE I'm seeing all 5 nodes, of which only one of them is shwoing is in Service. The rest of them are decommissioned.

I'm seeing a lot of information about removing the decommissioned nodes but very little on how to recommission. As far as cloudera manager is concerned, these nodes are active.

해결책

Well that is strange. Althought Cloudera manager thinks they're okay, I thought I'd try decommissioning the datanodes and then recommissioning them as a last ditch. It seems to have fixed the reporting as decommissioned

In addition its fixed my underreplication issue as well.
