    Hi @combineads, thanks for your patch.
    However, I'm sorry to say but this patch looks a sort of workaround to see the query progress. I think we need to devise a better solution.

> 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)
