I got the same error from beeline : beeline -u 'jdbc:hive2://server:10000/;principal=<Server_Principal_of_HiveServer2>'

I will be thankfull for your help.

is your hive Server is running in HTTP mode?

Connection URL When HiveServer2 Is Running in HTTP Mode:-

jdbc:hive2://<host>:<port>/<db>;transportMode=http;httpPath=<http_endpoint>

where:-

<http_endpoint> is the corresponding HTTP endpoint configured in hive-site.xml. Default value is cliservice.

Default port for HTTP transport mode is 10001.

Have you checked if hive services are running? Also server name is correct?

Is this a kerberos enabled cluster?

New Contributor

I have the same issue and in my case it is a Kerberos-enabled cluster. I modified the beeline command as follows:

 

${HIVE_HOME}/bin/beeline -u "jdbc:hive2://<server_name>:10015/default ssl=true;principal=<principal_name>/<hostname>@<REALM>;auth=kerberos; '' ''" "$@"

 

I get two errors:

- Unknown HS2 problem when communicating with Thrift server.

- Error: Could not open client transport with JDBC Uri: jdbc:hive2://<node_name>:10015/default: Invalid status 21 (state=08S01,code=0)

 

I would appreciate any help.

How do we check if Hive is running in Http mode?

I tried to search the same in hive-site.xml and found that http.mode <binary> be default.

In this case , can you please help me with this issue?

I may be able to provide analysis if you can post any error in hive server2 log.

First thing is to check if hive server2 is up and running properly.

@Ahmed Missaoui can you accept the best answer to close this thread?

  1. Kill your hiveserver2 & metastore & Restart them again.
  2. check hiveserver2 & metastore are running using 'jps' command.
  3. Run "root@hostname~]# beeline -u jdbc:hive2://localhost:10000/" .
  4. if still getting this error then replace "localhost" with "hostname " of step 3
  • These above steps has worked for me.

Expert Contributor

These can be few reasons :

1) other instance of database may be running .

2) namenode might be in safe mode

3) common localhost:9000 connection refused error.

Best way is to check the hive logs and debug it.

Expert Contributor

This happened to me. What I did was connect run the command below from beeline:

beeline> !connect jdbc:hive2://

Then, will ask for my user and pass, and i'm connected to my hive.

I'm having issues now connecting to hiveserver from Hue and Ambari View thou. 😞

EDIT:

I have 2 hiveserver2, hive metastore and webhcat servers.

There is kerboras keytab issue, please take new ticket and connect with HS2, it will work.

Hi All,

HiveServer2 is constantly going down and it works max for a day when we restart. The following is the error from hiveserver2 log when it is down.

I ran into similar problem as @Hari Krishnan Umapathy, my HiveServer2 was going down as soon as I started it. I recommend following steps to debug the:

- Check the error logs(.err) under - /var/log/hive

- Restart the service and put a tail on the new logs: tail -f hiverserver2.log

Note: I was running into out of memory error on my node and stopped some of the unwanted services and was able to bring up hive and beeline.
