Review request for Ambari, Balázs Bence Sári, Robert Levas, and Sebastian
Toader.
Bugs: AMBARI-21613
https://issues.apache.org/jira/browse/AMBARI-21613
Repository: ambari
Description
-------
Dynamically determine what keytab files have been distributed to hosts. A
custom command should be available via the KERBEROS_CLIENT to query for the
keytab files installed on the relevant host. The communication between the
Ambari server and the agents should generate data needed to determine what
keytab files exist.

Testing
-------
1.
- created a cluster with kerberos enabled
- deleted a keytab file from a host
- regenerated missing keytabs
- checked that the deleted keytab file was recreated
2.
- regenerated missing keytabs when no keytab files were missing
- checked that no keytab file was regenerated
3.
- created a 15 nodes cluster on openstack with services: HDFS, YARN, ZOOKEEPER,
SPARK1, SPARK2, HIVE
- measured the time taken to regenerate all keytabs and only missing keytabs:
regenerate missing keytabs only: 12.84 seconds (?=2.33)
regenerate all keytabs: 39.1 seconds (?=5.37)
existing tests: pending
Thanks,
Attila Magyar
