> 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
> 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.
