Connect to impala jdbc from an oozie java action

Connect to impala jdbc from an oozie java action

New Contributor

Is it possible to connect with an impala jdbc connection from inside an oozie job in a kerberized cluster?

 

Ideally there would be a way to pass a delegation token, but I see that there is no implementation for it in oozie, and I can't see anywhere that it is used.

 

(I don't have access to the keytab file, so I can't authenticate that way)

Hi @lev,

 

I assume you are looking for a way to authenticate with Impala JDBC similar to Hive JDBC described in chapter 'Using a Hadoop Delegation Token' here.

 

Impala JDBC/ODBC does not support this method, the current way to authenticate is to pass either the keytab or an LDAP password to the application. For example with a shell script that does the initialization.
