> NullPointerException after Datanodes Decommissioned and Terminated
> ------------------------------------------------------------------
>
> Key: HBASE-17501
> URL: https://issues.apache.org/jira/browse/HBASE-17501
> Project: HBase
> Issue Type: Bug
> Affects Versions: 1.2.0
> Environment: CentOS Derivative with a derivative of the 3.18.43
> kernel. HBase on CDH5.9.0 with some patches. HDFS CDH 5.9.0 with no patches.
> Reporter: Patrick Dignan
> Assignee: James Moore
> Priority: Minor
> Attachments: HBASE_17501.patch, HBASE_17501.patch,
> HBASE_17501.patch.v2, HBASE_17501.patch.v3
>
>
> We recently encountered an interesting NullPointerException in HDFS that
> bubbles up to HBase, and is resolved be restarting the regionserver. The
> issue was exhibited while we were replacing a set of nodes in one of our
> clusters with a new set. We did the following:
> 1. Turn off the HBase balancer
> 2. Gracefully move the regions off the nodes we’re shutting off using a tool
> we wrote to do so
> 3. Decommission the datanodes using the HDFS exclude hosts file and hdfs
> dfsadmin -refreshNodes
> 4. Wait for the datanodes to decommission fully
> 5. Terminate the VMs the instances are running inside.
> A few notes. We did not shutdown the datanode processes, and the nodes were
> therefore not marked as dead by the namenode. We simply terminated the
> datanode VM (in this case an AWS instance). The nodes were marked as
> decommissioned. We are running our clusters with DNS, and when we terminate
> VMs, the associated CName is removed and no longer resolves. The errors do
> not seem to resolve without a restart.
> After we did this, the remaining regionservers started throwing
> NullPointerExceptions with the following stack trace:
