I am deploying hive-metastore-3.0.0 using kerberos over DC/OS I have generated principal and keytab correctly and verified the same but while providing repective settings in metastore-site.xml still server showing error "Kerberos principal should have 3 parts:" its by default pickup my user "nobody or root" by which I run service but not the principal.
Rquest you to please help is there any addition property I have to set ?
My metastore-site.xml is:

Im getting error while connecting presto server to hive metastore.
Here is my hive.properties:
connector.name=hive-hadoop2
hive.metastore.uri=thrift://localhost:9083
hive.config.resources=/home/eweb/Downloads/hadoop/etc/hadoop/core-site.xml,/home/eweb/Downloads/hadoop/etc/hadoop/hdfs-site.xml
And here is my hive-site.xml :
<property>
<name>hive.metastore.uri</name>
<value>thrift://localhost:9083</value>
</property>
<property>
<name>hive.metastore.schema.verification</name>
<value>true</value>
</property>
<property>

I have tried this in terminal :
bin/presto --server localhost:8080 --catalog hive --schema bookvip
presto:bookvip> SHOW SCHEMAS;
Is there any kind of setup error or any other error ??
I just use the following commands step by step:
sudo netstat -tulpn | grep 9083
Then kill the process using this command
sudo kill -s 9 processid
And run once again
hive --service metastore
In my case, I missed to run the hive metastore service and so the error "Failed to connect to the MetaStore Server..."
To resolve, go to /usr/local/Cellar/hive/3.1.2_3/bin and run:
hive --service metastore
When I run:
hive --service hiveserver2 --hiveconf hive.server2.thrift.port=10000 --hiveconf hive.root.logger=INFO,console
It shows
Starting HiveServer2
and nothing listens on port 10000 and 10001
The HiveServer2 service does not output error information, causing it hard to diagnostic the problem. You can try to start the metastore service provided by Hive, which listens on port 9083 and might give some information when your configuration is not properly set:
hive --service metastore # not detach from terminal to see logs
In my case, this service cannot be started, with error message:
MetaException(message:Hive Schema version 3.1.0 does not match metastore's schema
version 1.2.0 Metastoed or corrupt)
One of the direct solution to resolve this error is to ignore the version difference by setting the hive-site.xml if there is only one hive version in your machine (another solution is to modify the metastore_db version):
<property>
<name>hive.metastore.schema.verification</name>
<value>false</value>
</property>
After this problem is resolved, the HiveServer2 service can be running and listening on port 10000.
hive --service hiveserver2 > /dev/null 2>&1 &
If your HiveServer2 access metastore via Derby or MySQL JDBC driver, then the aforementioned metastore service is not needed for HiveServer2. However, if HiveServer2 access metastore via thrift protocol, as configed in conf/hive-site.xml like
<property>
<name>hive.metastore.uris</name>
<value>thrift://hadoop-master:9083</value>
<description>
Thrift URI for the remote metastore.
Used by metastore client to connect to remote metastore.
</description>
</property>
Then, the metastore service must be started at first.
I had a hard time to set up hive-3.1.2. I write this maybe it helps someone out. in order to diagnose the problem first try to launch metastore and hiveserver2 like this:
metastore:
hive --service metastore --hiveconf hive.root.logger=INFO,console
hiveserver2:
hive --service hiveserver2 --hiveconf hive.server2.thrift.port=10000 --hiveconf hive.root.logger=INFO,console
then carefully read the the exceptions were thrown.
my problem was user hive is not allowed to perform this api call
and to solve that I added the following property to hive-site.xml:
<property>
<name>hive.metastore.event.db.notification.api.auth</name>
<value>false</value>
<description>
Should metastore do authorization against database notification related APIs such as get_next_notification.
If set to true, then only the superusers in proxy settings have the permission
</description>
</property>
also I add my full hive-site.xml as a sample:
<configuration>
<property>
<name>datanucleus.schema.autoCreateTables</name>
<value>true</value>
</property>
<property>
<name>javax.jdo.option.ConnectionURL</name>
<value>jdbc:mysql://server-2:3306/metastore?createDatabaseIfNotExist=true</value>
</property>
<property>
<name>javax.jdo.option.ConnectionUserName</name>
<value>mysql_username</value>
</property>
<property>
<name>javax.jdo.option.ConnectionPassword</name>
<value>mysql_password</value>
</property>
<property>

<property>

<value>false</value>
</property>
<property>
<name>hive.metastore.event.db.notification.api.auth</name>
<value>false</value>
</property>
</configuration>
Thanks. There is typo. It should hive.metastore not as shown below.
**metastore**.metastore.event.db.notification.api.auth
false
Failed to open new session: java.lang.RuntimeException:
org.apache.hadoop.ipc.RemoteException(org.apache.hadoop.security.authorize.AuthorizationException):
User: hadoop is not allowed to impersonate cheng
User:hadoop is my hadoop install use,and cheng is ubuntu user.
I have already the following configuration in my core-site.xml:
<name>hadoop.proxyuser.hive.hosts</name>
<value>*</value>
</property>
<property>
<name>hadoop.proxyuser.hive.groups</name>
<value>*</value>
</property>
the hive user is not exist before,so I change the hadoop.proxyuser.hive.groups to
hadoop.proxyuser.hadoop.group and so on.in hue config hue.ini,set the hue user.
so the problem is solution.
i just installed hive and mysql..
and copied the mysqlconnector to the hive_home/lib folder
but when i try show databases and create table commands in the hive> prompt giving me the error as below:
create database saty;

</property>
and i dont have a directory called /user/hive/warehouse in my file system.
i created these path with mkdir command.. and tried after reboot..
bout still getting the error..

Try Specifying these two properties
<property>
<name>javax.jdo.option.ConnectionUserName</name>
<value>username</value>
<description>Username to use against metastore database</description>
</property>
<property>
<name>javax.jdo.option.ConnectionPassword</name>
<value>password</value>
<description>Password to use against metastore database</description>
</property>
And Similarly the username of your mysql login should have the permission to access the db sepcified in the JDBC connection string. This Can be acheived using the following command
GRANT ALL ON Databasename.* TO username#'%' IDENTIFIED BY 'password';
The answer is located at http://www.cloudera.com/content/cloudera-content/cloudera-docs/CDH5/5.0/CDH5-Installation-Guide/cdh5ig_hive_schema_tool.html
To suppress the schema check and allow the metastore to implicitly modify the schema, you need to set the hive.metastore.schema.verification configuration property to false in hive-site.xml.
reconfigure your hive using -hiveconf hive.root.logger=warn,console than find the detail reason that why you could not instantiate your hive mate store client.
The problem i met was wrong mysql configuration, the error message is "Binary logging not possible. Message: Transaction level 'READ-COMMITTED' in InnoDB is not safe for binlog mode 'STATEMENT'". When i change binlog_format from "statement" to "binlog_format=mixed", then hive meta store client instantiate successfully.
Hope it work for you.
I had similar issue and the cause in my case was selinux where it prevented Postgres from proper running.
I inserted following line to the first line of /etc/rc3.d/S64postgresql -
echo 0 > /selinux/enforce # Disable selinux temporarily
and restarted the node with the hive metastore.
So generally you can check two things:
Check whether the DB for the metastore is running properly
Whether the user/passwd from the property is correct
