Hive metastore issue in HDp2.3.4.0

[#1]

We have configured HDP 2.3.4.0 with Ambari in CentOS 6.4. Post installation we can see that the Hive Metastore service is getting stopped everytime it is started through Ambari. We had chosen MySQL for Hive metastore but in logs we can see it tries to connect with Derby. Looking for your help.

Please check hive meta store settings in ambari and make sure that it's MySQL

[#3]

How to check it? Which file to check?

[#4]

@rajdip chaudhuri

It's in ambari console

[#5]

Ambari shows MySQL is being used. Attaching the screenshot.

For OOZIE we have selected New Derby Database. But for Hive we selected New MySQL db.

Hi......any suggestions please?

[#8]

@rajdip chaudhuri

In Hive server

cd /var/log/hive/

and read logs to troubleshoot further

[#9]

Hi Guys...looking for your help. We cannot connect to Hive post set up because of the issue.

Can you check mysql connectivity and past logs here. Can you also paste output of the following command.

SHOW GRANTS FOR 'hive';

And as Neeraj suggested please grant all privileges to hive user on host like below commend.

GRANT ALL PRIVILEGES ON *.* TO 'hive'@'<hive_host>' IDENTIFIED BY PASSWORD '<password>'

Also, very important

Run following in mysql as root user

grant all privileges on *.* to 'hive'@'host' identified by 'hivepassword' with grant option;
