-----------------------------------
Summary: renewable delegation tokens for long-lived spark
applications
Key: HBASE-15570
URL: https://issues.apache.org/jira/browse/HBASE-15570
Project: HBase
Issue Type: Improvement
Components: spark
Reporter: Sean Busbey
Assignee: Sean Busbey
Right now our spark integration works on secure clusters by getting delegation
tokens and sending them to the executors. Unfortunately, applications that need
to run for longer than the delegation token lifetime (by default 7 days) will
fail.
In particular, this is an issue for Spark Streaming applications. Since they
expect to run indefinitely, we should have a means for renewing the delegation
tokens.
