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

Is this a kerberos enabled cluster?

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.

  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.

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.
