From 284b15d2fbff7c0c3ffe8737838071d366ea5742 Mon Sep 17 00:00:00 2001 From: Reynold Xin Date: Fri, 22 Apr 2016 01:31:13 -0700 Subject: [SPARK-14826][SQL] Remove HiveQueryExecution ## What changes were proposed in this pull request? This patch removes HiveQueryExecution. As part of this, I consolidated all the describe commands into DescribeTableCommand. ## How was this patch tested? Should be covered by existing tests.
