Answer 1

I had a similar problem with hive server and followed the below steps:
1. Go to $HIVE_HOME/bin/metastore_db
2. Copied the db.lck to db.lck1 and dbex.lck to dbex.lck1
3. Deleted the lock entries from db.lck and dbex.lck
4. Relogin from hive shell. It is working
Thanks

Answer 2

I also was facing the same problem, and figured out that I had both hive-deafult.xml and hive-site.xml(created manually by me),

I moved my hive-site.xml to hive-site.xml-template(as I was not needed this file) then started hive, worked fine.
