Hi, We have cm_api scripts that create a multi-node CDH cluster, which are working fine. we've written a script that adds new hosts to cluster, inspect host and then apply host template. CMD_WAIT=30
try:
template.apply_host_template(host_ids=list(HOST),start_roles=True).wait(CMD_WAIT)
except Exception,err:
logger('warn',"Template issue, unable to apply Host template");
logger('error',err);
print(err); Template format : {
"clusterRef": {
"clusterName": "CLUSTERNAME"
},
"name": "DataNode_CLUSTERNAME",
"roleConfigGroupRefs": [
{
"roleConfigGroupName": "hbase-GATEWAY-BASE"
},
{
"roleConfigGroupName": "hdfs-DATANODE"
},
{
"roleConfigGroupName": "hdfs-GATEWAY-1"
},
{
"roleConfigGroupName": "hive-GATEWAY-BASE"
},
{
"roleConfigGroupName": "impala-IMPALAD"
},
{
"roleConfigGroupName": "spark_on_yarn-GATEWAY-BASE"
},
{
"roleConfigGroupName": "yarn-GATEWAY-1"
},
{
"roleConfigGroupName": "yarn-NODEMANAGER"
}
]
} Commands for adding Host, inspect and apply host template working fine, but after execution roles are not assigned to host. No Role is visible here. Kindly suggest
