Chenjian created AMBARI-25437:
---------------------------------
Summary: execution_command are running too slow
Key: AMBARI-25437
URL: https://issues.apache.org/jira/browse/AMBARI-25437
Project: Ambari
Issue Type: Improvement
Components: ambari-server
Affects Versions: ambari-server, 2.7.3
Reporter: Chenjian
Fix For: 2.7.3
when adding a service, this two interfaces will be requested 4 or 5 times each:
* POST
[http://ip:port/api/v1/stacks/SEA/versions/0.1/recommendations|http://10.128.142.193:8080/api/v1/stacks/SEA/versions/0.1/recommendations]
* POST
[http://|http://10.128.142.193:8080/api/v1/stacks/SEA/versions/0.1/validations]
[ip:port|http://10.128.142.193:8080/api/v1/stacks/SEA/versions/0.1/recommendations]
[/api/v1/stacks/SEA/versions/0.1/validations|http://10.128.142.193:8080/api/v1/stacks/SEA/versions/0.1/validations]
first interface costs about 38s, second interface cost about 34s, they both
call method StackAdvisorCommand.invoke(xxx), a synchronized function.
when changing Components configurations the two inteferfaces are also be
requested.
the above two interfaces make the UI too slow.
