custom command failed since jdk error

[Dai Xiang <xi...@sky-data.cn>]

Hi!

I follow docs to add a service to record hosts into a file, but it failed:

INFO 2018-01-31 02:49:07,731 ActionQueue.py:113 - Adding
EXECUTION_COMMAND for role write_ip for service null of cluster null to the queue.
INFO 2018-01-31 02:49:07,772 ActionQueue.py:238 - Executing command with id = 29-0, taskId = 257 for role = write_ip of cluster null.

Traceback (most recent call last):

  line 324, in runCommand
      server_url_prefix = command['commandParams']['jdk_location']
      KeyError: 'jdk_location'

The call cmd is as below:

curl --user admin:admin -X POST -H 'X-Requested-By:ambari' -d '{"RequestInfo":{"context":"Write Ip Config","action":"write_ip","parameters":{"host_list":"2ceed4a520de"}},"Requests/resource_filters":[{"hosts":"2ceed4a520de"}]}' http://localhost:8080/api/v1/requests

Could someone help me?
