Background

The above output is an attempt of Ambari trying to initiate the hive metastore process based on the parameters supplied in the following properites

javax.jdo.option.ConnectionDriverName
javax.jdo.option.ConnectionURL
javax.jdo.option.ConnectionUserName	

This is mostly not required if all the credentials are aligned, however, its possible we might end up with such issues when we are trying to use customized DB access. The above error is relevant to mysql db as metastore repository, however, same principal can be applied to other DBs as well.

Mysql's authentication mechanism allows user/host credentials to be defined in a certain order. Here is an example.

mysql> use mysql;
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A


Database changed
mysql> select user,host from user;
+------+-----------------------+
| user | host                  |

| root | localhost             |
| hive | node1.hortonworks.com |
| root | node1.hortonworks.com |
| hive | node2.hortonworks.com |
| hive | node3.hortonworks.com |

We can verify the error as indicated by the ambari log output at mysql level, using the superuser access, because this is what Ambari server is trying to do.

[root@node1 ~]# mysql -u hive -h node1.hortonworks.com -p 
Enter password: 
ERROR 1045 (28000): Access denied for user 'hive'@'node1.hortonworks.com' (using password: YES)

How-to-fix

  • Observe the output before exception from Ambari log, look at the username, password and the command string which is being attempted.
resource_management.core.exceptions.Fail: Execution of 'export HIVE_CONF_DIR=/usr/hdp/current/hive-metastore/conf/conf.server ; /usr/hdp/current/hive-server2-hive2/bin/schematool -initSchema -dbType mysql -userName hive -passWord [PROTECTED] -verbose' returned 1. which: no hbase in (/usr/sbin:/sbin:/usr/lib/ambari-server/*:/usr/sbin:/sbin:/usr/lib/ambari-server/*:/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.111-1.b15.el7_2.x86_64/jre/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin:/var/lib/ambari-agent:/var/lib/ambari-agent)
  • If you are not using the root user, ensure that you add another property to hive-site.xml i.e., javax.jdo.option.ConnectionPassword with password for the user that is configured for property javax.jdo.option.ConnectionUserName
  • At mysql level, login as root user and grant with the following syntax (you might need to execute 'flush privileges' post this, not necessary. We do need to note that if you do not specify "identified by", the error would still remain even though the user 'hive' has been configured to be identified by 'password' which was set while creating the user.
mysql> grant all on *.* to 'hive'@'node1.hortonworks.com' identified by 'changeme';
Query OK, 0 rows affected (0.00 sec)
  • Even if local to the host, test out if you are able to login with the supplied credentials
[root@node1 ~]# mysql -u hive -h node1.hortonworks.com -p

Hello i've performend all steps

creating and granting privileges. But it still says this. But if I try to login using that user 'hive'@'metastore_fqdn' I'm able to login using password provided.

But if I restart the hive it still says same error. Please some help.
