Adding A Table In HIVE Does Not Create A Table On Mysql Which Is The Metastore

 

 

Hi,

 

I have configured remote metastore(mysql) for hive.

I created a table in hive using oozie. But still 'select * from TBLS' remains empty.

The oozie job is successful. No errors are thrown in the log. But not able to see any info in mysql metastore.

The configuration details are given below,

Hive-site.xml

Posted by Alan Gates <al...@gmail.com>.

Your hive-site.xml referenced a metastore service at localhost:9083.  
Did you start it with this same hive-site.xml?
