Can you search your /tmp/<username>/hive.log for 'Stats' and see if there is any error message? You can also log on to mysql and see if the database you specified in the JDBC URI has been created and if there is any table in the database.

Try to copy-paste one of the existing properties sections and pasting over just the name and value strings from the message.

I'm trying to gather statistics for tables by using the autogather functionality. It works for the size of the table and the number of files, but when I use the ANALYZE command, it tells me 'could not update stats' and no row counts are computed. I followed the instructions on the wiki and set autogather to true, I also replaced the parameters like this: set hive.stats.dbclass=jdbc:mysql; set hive.stats.dbconnectionstring="jdbc:mysql://localhost/mstore"; set hive.stats.jdbcdriver="org.apache.mysql.jdbc.EmbeddedDriver"; The problem with the second parameter was that whenever I specified something after the ';' like suggested in the wiki, it threw an error. Does anyone have suggestions what might be wrong? Thanks, Anja
