Xiao Li commented on SPARK-19115: --------------------------------- When the location of the table is not user provided, it will be a managed table. It is not a bug, but by design. > 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 . -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
