[jira] [Created] (AMBARI-4708) Actual configs not updated after
restart of host component
Dmytro Sen created AMBARI-4708:
----------------------------------
Summary: Actual configs not updated after restart of host component
Key: AMBARI-4708
URL: https://issues.apache.org/jira/browse/AMBARI-4708
Project: Ambari
Issue Type: Bug
Components: agent, controller
Affects Versions: 1.5.0
Reporter: Dmytro Sen
Assignee: Dmytro Sen
Priority: Critical
Fix For: 1.5.0
Updated HDFS configs aren't applied after RESTART.
Steps:
- On a 3 node cluster, create a ConfigGroup for datanode.
- Override heap size to 1025m instead of 1024m
- Restart DN.
Result:
- The /var/lib/ambari-agent/data/config.json, has the correct values for the config type:
{code}
"global": {"2": "version1392171779044", "tag": "version1"}
{code}
- The API call still shows global as default version:
{code}
http://hostname1:8080/api/v1/clusters/c1/hosts/hostname1/host_components/DATANODE
{code}
Note:
It works after agent is restarted.
{code}
{
global: {
overrides: {
2: "version1392171779044"
},
default: "version1"
}
{code}
The cause is that hooks aren't executed for the custom_command like RESTART. Since configs for HDFS are generated in hook.py, we must execute hook.py before custom commands or move config generation from hook.py.
