Subject: Re: Hive Statistics information
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?
Regards

Hi guys
I have configured Hive to use MySQL for all statistics
hive.stats.atomic=false
hive.stats.autogather=true
hive.stats.collect.rawdatasize=true
hive.stats.dbclass=jdbc:mysql
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>
hive.stats.jdbc.timeout=30
hive.stats.jdbcdriver=com.mysql.jdbc.Driver
hive.stats.retries.max=0
hive.stats.retries.wait=3000
However in the MYSQL hive statistics tables , they don't seem to have any data ?
Where does Hive store the statistics information ?
