Moving Hbase region server to new host

[#1]

I am having 5 region servers in my cluster, I have added an additional 5 region servers,

can I directly decommission the older 5 region server with the help of ambari server, will it cause any data loss in HBase?

Hi @KPG1 ,

I have found a another cloudera article similar to your concern, Please check the below link:

Hi @ChethanYM ,

Thanks for the help,

gracefully shutting down the region server triggers the hbase Master to perform a bulk assignment of all regions hosted by that region server.
