Unable to connect to beeline

avatar
Contributor

Hello,


I am not able to connect to beeline. It is throwing error as "connection refused". I was able to see hive server2 service and hive metastore service is up and running through ambari UI. I am using the below command to connect

beeline -u 'jdbc:hive2://headnodehost:10001/;transportMode=http'

below is the error:

As you mentioned that "netstat" command itself is not showing that the port 10001 is opened then definitely you can not connect to it using "beeline" or "telnet" utilities.

Check the following and then try to provide us as much information which we requested in previous post. All the command outputs and the configs which we requested you to check.


Check-1). Hence please check your HiveServer2 log first to find out what might be wrong? Please restart HS2 and then collect a fresh log from "/var/log/hive/hiveserver2.log"

Check-2). What is the value of following hive properties?

"hive.server2.transport.mode"

"hive.server2.thrift.http.path"

Check-3). Please share the output of the following (or screenshot of the exact error)

Ambari UI --> Hive --> Summary (Tab) --> "HiveServer2 JDBC URL" --> Click on the at the right side of the URL to copy the URL and then try this URL with beeline once.

As you mentioned that you got "no such file or directory found." So please share the complete output of the error .


Check-4). May be your "hive.server2.transport.mode" is set to "binary" (default value) so in that case please check if the following approach works on port 10000 (instead of http mode 10001).

# beeline -u "jdbc:hive2://headnodehost:10000/default"

Earlier you mentioned that you could not find port 10001 being opened. Hence you were getting "(Connection refused) (state=08S01,code=0)" error.

# netstat -tnlpa | grep `cat /var/run/hive/hive-server.pid`   


Now if you are curently able to see that Port 10001 is listening then in that case you can try to login using default "hive" / "hive" to see if it works? Ideally any valid user who has access to Hive DB should be able to connect via beeline.

.


If you still face any error then please share the complete stack trace of the error.

Also if your current issue is different from the Originally reported issue "(Connection refused) (state=08S01,code=0)" then please open a separate HCC thread and mark this HCC thread as answered by clicking on the "Accept" button on correct/helpful answer.

Thank you.As mentioned earlier netstat -tnlpa | grep `cat /var/run/hive/hive-server.pid` itself is not showing port 10001. Below is the error stack
