Dear all,

I'm installing CDP private cloud base and i have installed Hive, Hive on Tez, Impala and Kudu services on the cluster

But for my use case i don't want impala to see hive database because i will use impala to work with kudu and i will use hive on tez to work with hive.

So, how can i separate impala from hive ?

@dv_conan Although in Impala docs it says, you could use a metastore db directly without using Hive metastore service, it is not recommended.

https://impala.apache.org/docs/build/html/topics/impala_prereqs.html

In Cloudera CDP, you could not remove the dependency between Hive and Impala. Under Impala Configuration, you will see a greyed out tick box for Hive, which means it's not optional.
