-------------------------------------------
Summary: Reassign Master: Parse create component resource and
delete component resource request response on failure.
Key: AMBARI-3668
URL: https://issues.apache.org/jira/browse/AMBARI-3668
Project: Ambari
Issue Type: Task
Components: client
Affects Versions: 1.4.2
Reporter: Aleksandr Kovalenko
Assignee: Aleksandr Kovalenko
Fix For: 1.4.2
h5. Resource create request:
Reassign Master wizard Step-4: Configure Components has a command that creates
component resource on the target host and it's displayed as Create <component
name>.
If this API results in failure because the resource already exists, then we
receive json response:
{
"status" : 409,
"message" :
"org.apache.ambari.server.controller.spi.ResourceAlreadyExistsException:
Attempted to create a host_component which already exists: \[clusterName=c1,
hostName=c6402.ambari.apache.org, componentName=ZOOKEEPER_SERVER]"
}
Parse the response on API failure and if it's because of
org.apache.ambari.server.controller.spi.ResourceAlreadyExistsException then
*mark the command as successful instead of failed*.
h5. Resource delete request:
We have a delete disabled <component_name> command on either step4 (if there
are no manual steps) or step6 (if there are manual steps).
If the command fails because the resource is already deleted then the json
response received is:
{
"status" : 404,
"message" : "org.apache.ambari.server.controller.spi.NoSuchResourceException:
The specified resource doesn't exist: ServiceComponentHost not found,
clusterName=c1, serviceName=HDFS, serviceComponentName=NAMENODE,
hostName=c6402.ambari.apache.org"
}
Parse the response on API failure and if it's because of
org.apache.ambari.server.controller.spi.NoSuchResourceException then *mark the
command as successful instead of failed*.
