I am using Hadoop-2.6.0 secured with kerberos. Installed hive server2 1.1.0 version with derby database as connectionurl, enabled security and enabled Authorization. When enabling transaction configuration, I am getting the below exception and cannot execute any queries;
Exception
Error: Error while compiling statement: FAILED: LockException [Error 10280]: Error communicating with the metastore (state=42000,code=10280)
Logs
[Error 10280]: Error communicating with the metastore org.apache.hadoop.hive.ql.lockmgr.LockException: Error communicating with the metastore at org.apache.hadoop.hive.ql.lockmgr.DbTxnManager.getValidTxns(DbTxnManager.java:300) at org.apache.hadoop.hive.ql.Driver.recordValidTxns(Driver.java:927)
Caused by: MetaException(message:Unable to select from transaction database, java.sql.SQLSyntaxErrorException: Table/View 'TXNS' does not exist.
So i have created a below property in hive-site.xml file as mentioned in a blog here
Configuration
<property>
<name>hive.in.test</name>
<value>true</value>
</property>
If i set the above property then getting the below exception where i am struck and unable to solve it. I cannot run any query even use mydb;
Exception
Error: Error while compiling statement: FAILED: NullPointerException null (state=42000,code=40000)

I need a solution to work ACID transactions in Hive Server2. I found two related questions but not solved my issue.
