The Hive client library is not smart enough to notice that the current user is a proxy user; so when using a proxy user, it fails to fetch delegation tokens from the metastore because of a missing kerberos TGT for the current user. To fix it, just run the code that fetches the delegation token as the real logged in user. Tested on a kerberos cluster both submitting normally and with a proxy user; Hive and HBase tokens are retrieved correctly in both cases. Author: Marcelo Vanzin <vanzin@cloudera.com> Closes apache#11358 from vanzin/SPARK-13478. (cherry picked from commit c7fccb5)

There was a minor conflict but otherwise a trivial backport. Just running tests to make sure. |
