Description
Hi,
I've been trying to get the config validation states for each service (specifically validationState and validationMessage fields) from the CM API as documented here:
http://cloudera.github.io/cm_api/apidocs/v1/el_ns0_configList.html
but it doesn't seem to be returned as part of the json. I'm connecting with valid credentials to the admin account. Here's the output from the CDH 4.6 cluster which is the same for v1 and v2 of the API:
GET http://x.x.x.x:7180/api/v2/clusters/Cluster 1/services/mapreduce/config
returns:
{
"roleTypeConfigs" : [ {
"roleType" : "GATEWAY",
"items" : [ {
"name" : "mapred_submit_replication",
"value" : "1"
} ]
}, {
"roleType" : "JOBTRACKER",
"items" : [ {
"name" : "jobtracker_java_heapsize",
"value" : "52428800"
}, {
"name" : "jobtracker_mapred_local_dir_list",
"value" : "/mapred/jt"
} ]
}, {
"roleType" : "TASKTRACKER",
"items" : [ {
"name" : "mapred_tasktracker_instrumentation",
"value" : "org.apache.hadoop.mapred.TaskTrackerCmonInst"
}, {
"name" : "mapred_tasktracker_map_tasks_maximum",
"value" : "1"
}, {
"name" : "mapred_tasktracker_reduce_tasks_maximum",
"value" : "1"
}, {
"name" : "task_tracker_java_heapsize",
"value" : "52428800"
}, {
"name" : "tasktracker_mapred_local_dir_list",
"value" : "/mapred/local"
} ]
} ],
"items" : [ {
"name" : "hdfs_service",
"value" : "hdfs2"
} ]
}
Is this something that was meant to be implemented but never was or am I missing something?
I also tried v1-5 of the API, v1 and v2 appear to give the same output while v3 onwards are not implemented (that's documented though).
Thanks
