[jira] [Updated] (SPARK-16942) CREATE TABLE LIKE generates External
table when source table is an External Hive Serde table
[ https://issues.apache.org/jira/browse/SPARK-16942?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Xiao Li updated SPARK-16942:
----------------------------
Description:
When the table type of source table is an EXTERNAL Hive serde table, {{CREATE TABLE LIKE}} will generate an EXTERNAL table. The expected table type should be MANAGED
The table type of the generated table is `EXTERNAL` when the source table is an external Hive Serde table. Currently, we explicitly set it to `MANAGED`, but Hive is checking the table property `EXTERNAL` to decide whether the table is `EXTERNAL` or not. (See https://github.com/apache/hive/blob/master/metastore/src/java/org/apache/hadoop/hive/metastore/ObjectStore.java#L1407-L1408) Thus, the created table is still `EXTERNAL`.
