Ambari启动hive报错

第一次错误：

Traceback (most recent call last):

resource_management.core.exceptions.Fail: Failed to download file from http://ice5.ibm.com:8080/resources//mysql-connector-java.jar due to HTTP error: HTTP Error 404: Not Found

可以看到是因为没有 

mysql-connector-java.jar

去 ice5 这台机器安装一下 

sudo yum install mysql-connector-java*

ls -al /usr/share/java/mysql-connector-java.jar

cd /var/lib/ambari-server/resources/

ln -s /usr/share/java/mysql-connector-java.jar mysql-connector-java.jar

再次运行，依然报错，

org.apache.hadoop.hive.metastore.HiveMetaException: Failed to get schema version.
Underlying cause: java.sql.SQLException : Access denied for user 'hive'@'ice5.ibm.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.

1. 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.
• 这里的 changeme 改成 你配置 hive 时设置的密码

1. mysql> grant all on *.* to 'hive'@'node1.hortonworks.com' identified by 'changeme';
2. 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

1. [root@node1 ~]# mysql -u hive -h node1.hortonworks.com -p
2. Enter password:
