Why not all parameters from ambari cluster not represented by the blueprint json file

Question

Why not all parameters from ambari cluster not represented by the blueprint json file ?

I generated the blueprint json file as the foolwing:

 curl -u admin:admin -H "X-Requested-By: ambari" -X GET http://10.23.4.122:8080/api/v1/clusters/HDP01?format=blueprint -o /tmp/HDP01_blueprint.json

but when I access to the ambari GUI we noticed that many parameters not appears in the blueprint json file

example of parameters from HDFS – config that not appears in the blueprint json file

DataNode failed disk tolerance

DataNode maximum Java heap size

DataNode max data transfer threads

You should be seeing all parameters in output json file.

For few parameters Ambari GUI shows different names. Example:

DataNode failed disk tolerance - appears as dfs.datanode.failed.volumes.tolerated in ouput json

DataNode maximum Java heap size - appears as dtnode_heapsiz in ouput json

DataNode max data transfer threads - appears as dfs.datanode.max.transfer.threads in ouput json

first of all thank you so much , so how we can find each parameter from ambari GUI that is relevant to the json ( as you know we have more then 3000 parameters ) how we can handle this ? – King David Aug 15 '17 at 16:30
btw - do you have chance to give me tip about my previous question - https://stackoverflow.com/questions/45688805/how-to-convert-blueprint-json-file-to-csv-file – King David Aug 15 '17 at 16:38
@David, please accept answer if you are satisfied with it. About your question in comment- you will find parameter actual name and display name mapping in /var/lib/ambari-server/resources/common-services///configuration/ e.g. /var/lib/ambari-server/resources/common-services/HDFS/2.1.0.2.0/configuration/hdfs-site.xml – Shubhangi Aug 15 '17 at 16:40
under the folder we see only that - core-site.xml hadoop-env.xml hadoop-policy.xml hdfs-log4j.xml hdfs-logsearch-conf.xml hdfs-site.xml ssl-client.xml ssl-server.xml ( but I think we have alot of missing parameters that not defined on the xml above ) – King David Aug 15 '17 at 16:50
@David, I think you are referring /var/lib/ambari-server/resources/common-services/HDFS/2.1.0.‌2.0/configuration directory , which will include only HDFS service related files. Please check configurations directory for other services such as HIVE, HBASE etc – Shubhangi Aug 15 '17 at 16:54
