Hi, IMO, 'org.apache.hadoop.hive.ql.lockmgr.DbTxnManager' is used for hive
native acid table, not for Iceberg table.
The lock mechanism in Iceberg table is controlled by HMS Catalog or other
Iceberg Catalog(JDBC catalog, etc). So
'org.apache.hadoop.hive.ql.lockmgr.DbTxnManager' should not be us
I am experiencing a possible deadlock issue while working with Hive version
4.1.0. The issue occurs when an 'insert overwrite' query is executed on an
Iceberg table. Specifically, I have found that if the 'hive.txn.manager'
setting is 'org.apache.hadoop.hive.ql.lockmgr.DbTxnManager', a deadlock
