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
