Hi All,
I'm caught up with the error pasted below after trying to use hive
transaction feature.I have followed this wiki to set required
configuration.
https://cwiki.apache.org/confluence/display/Hive/Hive+Transactions#HiveTransactions-Configuration
set hive.support.concurrency=true;
set hive.exec.dynamic.partition.mode=nonstrict;
set hive.txn.manager=org.apache.hadoop.hive.ql.lockmgr.DbTxnManager;
set hive.compactor.initiator.on=true;
set hive.compactor.worker.threads=1;
After setting the above I just ran this command "describe formatted
acidtest;"
any pointers as to why this occurs?

p.s : Before setting the transaction specific properties I was able to run
hive queries successfully
Thanks,
