Trouble-shooting

To add more useful information to stack-traces caused by RPC issues, the Config overrides documentation can be used to replace the default Netty implementation:

masters:
  roleGroups:
    default:
      configOverrides:
        hbase-site.xml:
          hbase.rpc.client.impl: "org.apache.hadoop.hbase.ipc.BlockingRpcClient"
regionServers:
  roleGroups:
    default:
      configOverrides:
        hbase-site.xml:
          hbase.rpc.client.impl: "org.apache.hadoop.hbase.ipc.BlockingRpcClient"
