------------------------------------
Summary: Failure saving configuration in a new Host Config Group
Key: AMBARI-4455
URL: https://issues.apache.org/jira/browse/AMBARI-4455
Project: Ambari
Issue Type: Bug
Components: client
Affects Versions: 1.4.3
Reporter: Andrii Tkach
Assignee: Andrii Tkach
Priority: Blocker
Fix For: 1.4.4
1) Clean install, new cluster, HDP 1.3.3 stack
2) using Ambari 1.4.3
3) Two nodes (one with NN, other with SNN) -- both with DN, TT
4) create new HDFS group, put a host in the group, click save
5) You return to Ambari with that new group set as the group.
6) Filter to find a prop
7) Override one property
8) Click save, failure message
Saw PUT error. Attaching screen shots.
The issue is reproducible based on Step 5. Seems if you create a new group and
save, when that group is set in the UI and you try to save, it PUTs the
config_group w/o the id, causing the PUT failure.
/api/v1/clusters/MyCluster/config_groups/ is being called and not
/api/v1/clusters/MyCluster/config_groups/*\{id}* (id is not set)
I have seen that PUT failure surface as "failure to save" message as well as
"silent failure" where the message says successfully saved but the PUT failed
under-the-hood.
