Hi,
While removing Impala i have getting the warning that to remove Hue,Hive & oozie before removing Impala.
I removed the impala on below steps :
CM UI –> Impala Instances –>Role Type–>Select all Role Type from Action Tab and select stop option .
Once all the roles are stopped , go to CM UI –> Impala Service drop down option and select Delete and confirm.
It Giving a warning to first remove Hue,Oozie,Hive as they are the dependencies of Impala
as we have some users in Hue and many tables in Hive as the system.
some users added and many tables are created in Hive
If suppose i remove Hue Hive & oozie to remove Impala then how to restore these service back in inital stage.
Like all the user should be inherited once we reinstall/reconfigure Hue & all the tables we have created before in
Hive should be there once we reinstall/reconfigure Hive & all the users in Hue.
Can you please share some step how to remove Impala service without affecting other services like Hue, Hive & oozie without any data loss.
Thanks,
Ankush
