> When query metrics are enabled on prepare query, seeing following issues :
> {noformat}
> lens-shell>prepQuery explain cube select id,name from sample_dim
> Explain FAILED:A metric named lens.MethodMetricGauge.5a82d69f-8968-44f4-af08-cb4a6d65b12a-HiveDriver-org.apache.lens.driver.cube.RewriteUtil-rewriteQuery already exists
> {noformat}
> The above happens because the driver config merge went wrong.
> Once it is fixed seeing the below :
> {noformat}
> lens-shell>prepQuery  explain cube select id,name from sample_dim
> Command failed javax.ws.rs.InternalServerErrorException: HTTP 500 A metric named lens.MethodMetricGauge.3d83e617-68a4-4695-ac5e-801392b0b9bc-JDBCDriver-columnar-sql-rewrite already exists
> {noformat}
> This happens because prepare happens once for validate and once for prepare.
