Abhishek Talluri commented on HBASE-15570: ------------------------------------------ Is there any update if this has been handled in spark2 .. It's confusing to see SPARK-14743 moved to resolved state and this remains unresolved. I have a client who is looking for automatic renewal of HBase delegation token and we are unsure if this has been fixed. > 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 > Priority: Major > > 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. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
