> In HMS, I noticed that all the filter hooks are applied on the client side (in HiveMetaStoreClient.java).
Is there any reason why we can't apply the filters on the server-side?
> Motivation: Some newer apache projects such as Kudu use HMS for metadata storage. Kudu
is not completely Java-based and there are interaction points where they have C++ clients.
In such cases, it would be ideal to have consistent behavior from HMS side as far as filters,
etc are concerned.
