Hive/SOLR/HBase Restart Needed After Adding DataNodes?

[ Edited ]

Hi All, if we add a few additional DataNodes to our cluster, and then execute a rebalance, do the dependent services (Hive, Impala, SOLR, Flume, etc) require an immediate restart or can they run with a stale configuration for a week or so until we can schedule it?

 

The DataNodes will include the following roles:

  • HBase RegionServer
  • HDFS DataNode
  • Impala Daemon
  • Solr Server
  • YARN NodeManager

Thank you.

Hi @DataMike,

 

You need to restart all afected component. If not this will run like nothing.
