Xiaochen Ouyang updated SPARK-19115:
------------------------------------
Description:
spark2.0.1 unsupports the command " create external table if not exist new_tbl like old_tbl "
we tried to modify the sqlbase.g4 file,change
" | CREATE TABLE (IF NOT EXISTS)? target=tableIdentifier
LIKE source=tableIdentifier #createTableLike"
to
" | CREATE EXTERNAL? TABLE (IF NOT EXISTS)? target=tableIdentifier
LIKE source=tableIdentifier #createTableLike"
and then we compiled spark and replaced the jar "spark-catalyst-2.0.1.jar" ,after that,we found we can run command "create external table if not exist new_tbl like old_tbl" successfully,unfortunately we found the generated table's type is MANAGED_TABLE other than EXTERNAL_TABLE in metastore database .
