---------------------------------------
Summary: SparkSQL unsupported the command " create external table
if not exist new_tbl like old_tbl"
Key: SPARK-19115
URL: https://issues.apache.org/jira/browse/SPARK-19115
Project: Spark
Issue Type: Bug
Components: SQL
Affects Versions: 2.0.1
Environment: spark2.0.1 hive1.2.1
Reporter: Xiaochen Ouyang
spark2.0.1 unsupported 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 .
