Review request for Ambari, Myroslav Papirkovskyy, Sid Wagle, and Vitalyi
Brodetskyi.
Bugs: AMBARI-19388
https://issues.apache.org/jira/browse/AMBARI-19388
Repository: ambari
Description
-------
When you are trying to disable security om perf cluster it fails.
1) For cluster with 1200 agents it works fine but for cluster with 1850 agents
it fails.
2) According to what i found, root cause is PUT request to
http://<ambari_server_host>:8080/api/v1/clusters/<cluster_name> with data like
"security_type" : "NONE". So, this request trying to change security type from
KERBEROS to NONE and fails by timeout of three minutes.
3) Interesting thing, request to change security type fails and UI showing
Error on disable security window. But in the same time in BG operations process
which destroying keytabs proceed work.
4) One more thing. After failed disabling kerberos, if you will click restart
the same request(update security type) will finish work in a few seconds.
So, what we need to do is to connect profiler and find out what exactly take so
much time for request to change security type.
