Description

We submit blueprint with configurations (core-site):

{"Blueprints":

{ "blueprint_name": "bp1_simple", "stack_name": "HDP", "stack_version": "2.2" }

,
"host_groups": [
{
"name": "master_1",
"cardinality" : "1",
"components": [

{ "name": "JOURNALNODE" }

,

{ "name": "NAMENODE" }

,

{ "name": "ZKFC" }

,

{ "name": "ZOOKEEPER_SERVER" }

,

{ "name": "DATANODE" }

,

{ "name": "NODEMANAGER" }

,

{ "name": "HDFS_CLIENT" }

,

{ "name": "MAPREDUCE2_CLIENT" }

,

{ "name": "YARN_CLIENT" }

,

{ "name": "ZOOKEEPER_CLIENT" }

]
},
{
"name": "master_2",
"cardinality" : "1",
"components": [

{ "name": "APP_TIMELINE_SERVER" }

,

{ "name": "JOURNALNODE" }

,

{ "name": "RESOURCEMANAGER" }

,

{ "name": "ZOOKEEPER_SERVER" }

,

{ "name": "DATANODE" }

,

{ "name": "NODEMANAGER" }

]
},
{
"name": "master_3",
"cardinality" : "1",
"components": [

{ "name": "JOURNALNODE" }

,

{ "name": "RESOURCEMANAGER" }

,

{ "name": "NAMENODE" }

,

{ "name": "ZKFC" }

,

{ "name": "ZOOKEEPER_SERVER" }

,

{ "name": "DATANODE" }

,

{ "name": "NODEMANAGER" }

]
}
}
"configurations": [
{
"core-site": {
"properties" : {
"fs.defaultFS" : "hdfs://mycluster",
"ha.zookeeper.quorum" : "%HOSTGROUP::master_1%:2181,%HOSTGROUP::master_2%:2181,%HOSTGROUP::master_3%:2181"
}}
}
]
}

After "cluster assign" and "cluster create". The ambari-server still has the "%HOSTGROUP::master_1%" in corresponding hostname position and did not translate them.

We checked database those configs are added to table "blueprint-configuration" once the blueprint is added and never have chance to be changed even we change some "%HOSTGROUP::master_1%" to correct hostname through Ambari webUI.
