Ok, the next step is to look at the logs from your Hive metastore server
and see exactly what's happening. The error you're seeing is from the
client. On your metastore server there should be logs with the same
timestamp giving details on why the transaction operation failed.

Thanks Alan.
Yes I've run metastore scripts for oracle instance. Infact I've
removed my previous metastore and created a fresh one by running the
schema creation script for 1.2.1. I've looked into the new schema and
able to see the table TXNS. I've also removed the hdfs location
"/user/hive/warehouse" and created a fresh one.
But still I'm facing this issue.

Did you run the hive metastore upgrade scripts for your oracle
instance? This error message usually means the transaction related
tables have not been created in your database. Somewhere in your
distribution there should be a set of upgrade scripts. Look for
scripts of the form:
scripts/metastore/upgrade/oracle/upgrade-0.13.0-to-0.14.0.oracle.sql
You'll want to run all of the ones from 0.13 to 1.2 (0.13->0.14,
0.14->1.1, 1.1->1.2). The 0.13->0.14 scripts assume that you added
the transaction tables as part of upgrading to Hive 0.13. If you did
not you will need to first run hive-txn-schema-0.13.0.oracle.sql which
will create the initial transaction tables. You can determine whether
this was done by looking for a table named TXNS in the hive schema on
your Oracle db.

Hi All,
Earlier I was using hive 0.13.0 and now trying to migrate to latest
version to utilize the transaction support introduced from hive 0.14.0.
I downloaded hive 1.2.1, created a metastore in oracle database and
provided all the required configuration parameters in
conf/hive-site.xml to enable transactions. For the parameter
"hive.txn.manager" given the value
"org.apache.hadoop.hive.ql.lockmgr.DbTxnManager".
From the hive prompt when I fire the command "show tables;" I'm
getting the below exception -
/FAILED: Error in determining valid transactions: Error communicating
with the metastore/
But if disable the "hive.txn.manager" parameter in hive-site.xml then
the command works fine.
Is there anything else to be configured which I'm missing?
Thanks & Regards,
Sarath.
