problem above, after installing hive 2.1.1, formatting was not successful, and did not find metastore (using mysql, but still fine before upgrade)


reason:

previously used hive 1.2.1, mysql connection metastore use user user is hive, may metadata deletion is not clean or some configuration file cannot be deleted,


solution:

USES another user.

mysql> create user 'hive1'@'%' identified by 'hive1';
mysql> grant all on *.* to 'hive1'@localhost identified by 'hive1';
mysql> flush privileges;

and modify: XML hive – site.

< property>
& lt; name> javax.jdo.option.ConnectionUserName< /name>
& lt; value> hive1< /value>
& lt; /property>

& lt; property>
& lt; name> javax.jdo.option.ConnectionPassword< /name>
& lt; value> hive1< /value>
& lt; /property>



this is the step required for hive2.0.

mysql> The SOURCE/home/raini/app/hive/scripts/metastore/upgrade/mysql/hive – schema – 2.1.0. Mysql. SQL;
