As Gopal said, you have to run a standalone metastore process for compactor to work.
More on that in

Please note that the transaction specific configuration properties in
are split into client and server groups.
The server group should be set in the config of the metastore process.

Subject: Re: Compactions doesn't launch on Hive 1.1.0

In logs i only see messages of DummyTxnManager, nothing about DbTxnManager.

When i connected to hive i use "set hive.txn.manager=org.apache.hadoop.hive.ql.lockmgr.DbTxnManager;".
How else i can configure transaction manager?

You can check the hive metastore log and confirm it also has the DbTxnManager
set up & that it is triggering the compactions.

Without a standalone metastore, the hive ACID compactor threads are not triggered.
