Subject Re: Flink-HBase connectivity through Kerberos keytab | Simple get/put sample implementation
Date Thu, 29 Sep 2016 17:48:02 GMT
Hi!

In Flink prior to 1.2, you can use Kerberos with HBase via Hadoop's
mechanism: https://ci.apache.org/projects/flink/flink-docs-
master/setup/config.html#kerberos

In Flink 1.2-SNAPSHOT, keytabs are installed in the Java security context,
from which HBase can probably pick it up. This is quite new (docs are not
yet updated), I'll let others chime in to add some more details.

@Max / @Vijay do you have any details?

Stephan
