Reply To: HDP 2.2 – issues starting services post-install

Hi Nigel,

I have installed HDP2.2 on Ambari 1.7 on a VM of single node. I am facing the same error you mentioned in this post, for HDFS datanode.

The hadoop datanode log file error message is :

FATAL datanode.DataNode (BPServiceActor.java:run(878)) – Initialization failed for Block pool <registering> (Datanode Uuid unassigned) service to hdp-hw-sandbox.cloudapp.net/1xx.11x.xx.xx:xxxx. Exiting.

I did a namenode format and tried, but no luck.

Any help is appreciated.

Thanks a lot
