We have HDP 2.4 cluster running HDFS, Yarn and HBase on 3 master and 4 data nodes.

Each data node hosts HBase RegionServer(8GB heap), HDFS Datanode, and Yarn Nodemanager. Each data node is amazon's d2.xlarge.

All master have ZK runnings. Other master processes are HDFS(HA), Hbase and Yarn(HA) masters. Each master node is amazon's r3.xlarge.

We see the following problems with two of our data nodes while other nodes function properly. Please note that MR or yarn jobs are not running when this happens :

1. Region Server dies with Zookeeper session timeout exceptions once in a while

3. Node becomes unresponsive sometimes(mostly after region server failure and continues to come on and off even though region server is no longer running), you can't login to it. AWS instance check fails. It comes back after few mins/few hours.

There is surely some network misconfiguration in the cluster but above issues happens only on few machines. The cluster is running in VPC. ulimit and nproc are set to 32768 and 65536 respectively. Most host metrics looks normal

Any ideas on debugging this would be greatly appreciated.

Thanks

It was DHCP failing to see a response from the DHCP server for periods of time. d2 Ubuntu(14.04) instances were using Enhanced Networking and the "ixgbevf" driver 2.11.3-k. 2.11.3-k is below the minimum recommended version 2.14.2 and should be upgraded to 2.16.4. We upgraded the driver to the latest version which seems to have fixed the issue.

NoRouteToHostException occurred in both region server and node manager logs.

Please check network connectivity.
