Impala JDBC Connection Failed Kerberos

[ Edited ]

Hi

In our cluster, impala service is working. Impala is accessible through HUE and impala-shell. But it got failed when I try to create JDBC connection in to it (Impala), through spark or talend.

This is my connection string when I try it through spark :
val con = DriverManager.getConnection ("jdbc:impala://myhost.supporting.mycompany.com:21050/default;AuthMech=1;KrbRealm=SUPPORTING.MYCOMPANY.COM;KrbHostFQDN=myhost.supporting.mycompany.com;KrbServiceName=impala;")

and this is my connection string when I try to connect through tImpalaConnection (talend)
jdbc:hive2://prodbdaast4dr.supporting.mycompany.com:21050/default;principal=impala/_HOST@SUPPORTING.MYCOMPANY.COM

But I always got error like this in spark:

java.sql.SQLException: [Cloudera][ImpalaJDBCDriver](500164) Error initialized or created transport for authentication: [Cloudera][ImpalaJDBCDriver](500169) Unable to connect to server: [Cloudera][ImpalaJDBCDriver](500591) Kerberos Authentication failed..

Re: Impala JDBC Connection Failed Kerberos

The first thing what came to my mind, do you have a valid ticket on all the spark/talend nodes? If not, then that is probably the root cause.

Re: Impala JDBC Connection Failed Kerberos

I do kinit on my driver node (edge node), and it works.

Do I need to make sure that my session is exist on each data node? How can I make sure that. I don't ever do this thing yet.

But when I try to create hive JDBC connection, it works. I think it should be same from the kerberos side, if hive works then impala should be works also.
