Description

It would be nice to check out query progress percentage in TAJO JDBC like TAJO CLI already did. The purpose is simple. I want to verify whether query is in block or not by monitoring query progress percentage.

While TAJO CLI uses display formatter, it would be nice to provide standard logging system in TAJO JDBC. That would be more convenient and make sense to let end users choose debugging level.

It would be helpful to print log messages such as an method below.
org.apache.tajo.client.TajoClientUtil.waitCompletion(QueryClient, QueryId)
