I want to check metadata of table such as column ,data type, and table name . So I tried to access hive meta store in mysql. I tried this query on mysql,I get the following Error.(I tried same query using root user, but it didn't work.)

How can I see this table?? or What is the best way for checking table metadata at once?

@tomoya yoshida,

Can you try connecting to mysql as below

mysql -uhive -p{password}

password is the password which you hive in ambari GUI while adding hive service.

Thanks,

Aditya

You can also run DESC <TABLE_NAME> command from CLI or BEELINE.
