Hi Sanjay, What do the logs say when you fire the ANALYZE TABLE... statement on a table ? One minor correction to the db connectionstring would be to use & for the query parameters. hive.stats.dbconnectionstring=jdbc:mysql://v-so1.nextagqa.com/hive_vso1_tempstatsstore?user=hive_user_vso1&password=hive_user_vso1<http://v-so1.nextagqa.com/hive_vso1_tempstatsstore?&user=hive_user_vso1&password=hive_user_vso1> I hope the database hive_vso1_tempstatsstore<http://v-so1.nextagqa.com/hive_vso1_tempstatsstore?&user=hive_user_vso1&password=hive_user_vso1> exists in your MySQL?
