Can we change rack assignment through cloudera manager

Can we change rack assignment through cloudera manager

Contributor

Hello All,

 

We are currently having the default rack configured for all our machines in our cluster.

 

And I want to assign different racks for the nodes.

 

Can I just do by assigning rack option in cloudera manager ? Or need to do some network related changes as well.

 

Please confirm.

 

Thanks,

No network change needed.

@Tomas79,

 

Have one more query.. Does rack toplogy applies to the datanodes only? and do we need to restart HDFS and YARN services after rack assignment.

 

Thanks,

No it applies to the Namenode and also YARN Resource Manager. I think you need to restart both, because YARN RM is displaying the rack location on its UI,.

@Tomas79,

 

Thank you. What if we have dedicated nodes for hive and hbase and other services. Can we include them as well into rack assignment? 

 

I believe there is no need to add edgenodes to rack assignment.

 

Please confirm.

 

Thanks,
