-------------------------------
Summary: Remove Duplicate Test Cases auto_join from
HiveCompatibilitySuite.scala
Key: SPARK-17052
URL: https://issues.apache.org/jira/browse/SPARK-17052
Project: Spark
Issue Type: Improvement
Components: SQL
Affects Versions: 2.0.0
Reporter: Xiao Li
The original [JIRA Hive-1642](https://issues.apache.org/jira/browse/HIVE-1642)
delivered the test cases `auto_joinXYZ` for verifying the results when the
joins are automatically converted to map-join. Basically, most of them are just
copied from the corresponding `joinXYZ`.
After comparison between `auto_joinXYZ` and `joinXYZ`, below is a list of
duplicate cases:
{noformat}
"auto_join0",
"auto_join1",
"auto_join10",
"auto_join11",
"auto_join12",
"auto_join13",
"auto_join14",
"auto_join14_hadoop20",
"auto_join15",
"auto_join17",
"auto_join18",
"auto_join2",
"auto_join20",
"auto_join21",
"auto_join23",
"auto_join24",
"auto_join3",
"auto_join4",
"auto_join5",
"auto_join6",
"auto_join7",
"auto_join8",
"auto_join9"
{noformat}
We can remove all of them without affecting the test coverage.
