Description

After reviewing some logs and errors emitted during a QTest run, I would like to propose some improvements to logging in HiveMetaStoreClient.

• Remove duplicate logging
• Remove superfluous class StackTraceLogger
• Do not use contractions in public-facing error messages and logs
• Make all logging side-effect free (see connCount)
• Code simplification
