> 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*.
