Xiao Li created SPARK-15838:
-------------------------------
Summary: CACHE TABLE AS SELECT should not replace the existing
Temp Table
Key: SPARK-15838
URL: https://issues.apache.org/jira/browse/SPARK-15838
Project: Spark
Issue Type: Bug
Components: SQL
Affects Versions: 2.0.0
Reporter: Xiao Li
Currently, {{CACHE TABLE AS SELECT}} replaces the existing Temp Table, if
existed. This behavior is different from `CREATE TABLE` or `CREATE VIEW`. It
looks risky.
