----------------------------------------------
Summary: Prevent Spark trying for token which is already available
Key: OOZIE-2531
URL: https://issues.apache.org/jira/browse/OOZIE-2531
Project: Oozie
Issue Type: Improvement
Reporter: Satish Subhashrao Saley
Assignee: Satish Subhashrao Saley
As per [Apache Spark
documentation|http://spark.apache.org/docs/latest/running-on-yarn.html#spark-properties]
:
The property {{spark.yarn.security.tokens.service.enabled}} in Apache Spark
which controls whether to retrieve delegation tokens for non-HDFS services when
security is enabled. By default, delegation tokens for all supported services
are retrieved when those services are configured, but it's possible to disable
that behavior if it somehow conflicts with the application being run.
Currently supported services are: hive, hbase
It would be good to have default as
{{spark.yarn.security.tokens.hive.enabled=false}} to avoid having Spark
redundantly retry obtaining a token when it already has one (passed originally
from Oozie's hcat credentials).
