Rong Rong updated FLINK-11088: ------------------------------ Summary: Improve Kerberos Authentication Keytab discovery on YARN (was: Improve Kerberos Authentication using Keytab in YARN proxy user mode) > Improve Kerberos Authentication Keytab discovery on YARN > -------------------------------------------------------- > > Key: FLINK-11088 > URL: https://issues.apache.org/jira/browse/FLINK-11088 > Project: Flink > Issue Type: Sub-task > Components: Security, YARN > Reporter: Rong Rong > Assignee: Rong Rong > Priority: Major > > Currently flink-yarn assumes keytab is shipped as application master > environment local resource on client side and will be distributed to all the > TMs. This does not work for YARN proxy user mode [1] since proxy user or > super user might not have access to actual users' keytab, but can request > delegation tokens on users' behalf. > Based on the type of security options for long-living YARN service[2], we > propose to have the keytab file path discovery configurable depending on the > launch mode of the YARN client. > Reference: > [1] > https://hadoop.apache.org/docs/current/hadoop-project-dist/hadoop-common/Superusers.html > [2] > https://hadoop.apache.org/docs/current/hadoop-yarn/hadoop-yarn-site/YarnApplicationSecurity.html#Securing_Long-lived_YARN_Services -- This message was sent by Atlassian JIRA (v7.6.3#76005)
