Summary: convert token based authentication to kerberos/keytab
based
Key: SLIDER-474
URL: https://issues.apache.org/jira/browse/SLIDER-474
Project: Slider
Issue Type: Bug
Components: appmaster, security
Reporter: Jonathan Maron
Assignee: Jonathan Maron
The AM communication to HDFS and the localization performed by AM require an
authenticated identity or delegation tokens. However, tokens require quite a
bit of management to handle renewal and expiry. It is preferable to leverage a
keytab and authenticate via kerberos in the AM (the login identity) and use
that identity for managing the interactions.
