Change subject: IMPALA-12699: Set recv timeout for GetPartialCatalogObject Thrift RPC ...................................................................... IMPALA-12699: Set recv timeout for GetPartialCatalogObject Thrift RPC GetPartialCatalogObject RPCs was seen to hang in coordinator side caused by networking issue. Due to the piggyback mechanism of fetching metadata in local-catalog mode, a hanging RPC on shared metadata could block other queries. Since GetPartialCatalogObject RPCs are read-only requests, they can be cleanly retried. This patch creates a dedicated catalogd client cache for GetPartialCatalogObject RPC, and defines a flag variable for the RPC timeout. Testing: - Manually verified the metrics of the new catalogd client cache. - Passed the core tests.
