[jira] [Created] (GOBBLIN-1578) deregistration of hive table should not delete data
Arjun Singh Bora created GOBBLIN-1578:
-----------------------------------------
Summary: deregistration of hive table should not delete data
Key: GOBBLIN-1578
URL: https://issues.apache.org/jira/browse/GOBBLIN-1578
Project: Apache Gobblin
Issue Type: Bug
Reporter: Arjun Singh Bora
I found that Gobblin actually is not respecting the config hive.dataset.copy.deregister.fileDeleteMethod for unpartitioned tables
Here we call dropTable with default params [https://github.com/apache/gobblin/blob/master/gobblin-hive-registration/src/main/j[…]g/apache/gobblin/hive/metastore/HiveMetaStoreBasedRegister.java|https://github.com/apache/gobblin/blob/master/gobblin-hive-registration/src/main/java/org/apache/gobblin/hive/metastore/HiveMetaStoreBasedRegister.java#L528], which deletes the data as well. We should be calling it with deleteData=false like in [https://github.com/apache/gobblin/blob/master/gobblin-hive-registration/src/main/j[…]g/apache/gobblin/hive/metastore/HiveMetaStoreBasedRegister.java|https://github.com/apache/gobblin/blob/master/gobblin-hive-registration/src/main/java/org/apache/gobblin/hive/metastore/HiveMetaStoreBasedRegister.java#L549]
