--------------------------------------
Summary: Fetching delegation tokens for Hive fails when using
proxy users
Key: SPARK-13478
URL: https://issues.apache.org/jira/browse/SPARK-13478
Project: Spark
Issue Type: Bug
Components: YARN
Affects Versions: 1.6.0, 2.0.0
Reporter: Marcelo Vanzin
Priority: Minor
If you use spark-submit's proxy user support, the code that fetches delegation
tokens for the Hive Metastore fails. It seems like the Hive library tries to
connect to the Metastore as the proxy user, and it doesn't have a Kerberos TGT
for that user, so it fails.
I don't know whether the same issue exists in the HBase code, but I'll make a
similar change so that both behave similarly.
