Subject Re: Rebalance HDFS - Issue
Date Tue, 03 Nov 2015 04:25:20 GMT
Hi Sumit,

I have recently upgraded to Ambari 1.7 to 2.1.2-377 and HDP 2.2 to 2.3

I ran
http://mstd01.corp.com:8080/api/v1/clusters/BDP2_DEV/configurations?type=hdfs-site
output
of this url is attached.

There is saw it still displaying "stack_id" : "HDP-2.2", but my cluster
upgrade to HDP 2.3 and i can able to find my stack version in* Admin->Stack
and Version* tab.

Please suggest how can I proceed.

Thanks,
Shaik
