Chen Song commented on SAMZA-727: --------------------------------- I have successfully run this on our kerberized cluster for weeks. So far everything is good, except for the following: The current limitation only requests a HDFS delegation token at the start of the job submission. Since the delegation token will be expired after 7 days, it will have one limitation. * If the job needs interactions with HDFS (read or write) after 7 days, it may fail. * If there are tasks failed after 7 days, the AM may not be able to launch new containers because of expired HDFS token. So we can either * Go ahead and merge this one, and address the above later * Hold off and investigate options for the above one (we can use the approach using static keytab files, like what Slider uses) > Support for Kerberos > -------------------- > > Key: SAMZA-727 > URL: https://issues.apache.org/jira/browse/SAMZA-727 > Project: Samza > Issue Type: New Feature > Components: yarn > Affects Versions: 0.9.0 > Environment: YARN with Kerberos > Reporter: Qi FU > Assignee: Chen Song > Attachments: SAMZA-727.patch > > > Samza doesn't support Kerberos, which is very common for YARN cluster. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
