from ambari we can capture all version , by click on Admin button and the click on stack and version
finally click on Versions , then we get the following details
we want to know how to capture all these version by using ambari rest api?
we try
curl -u admin:admin -H 'X-Requested-By:admin' 'http://localhost:8080/api/v1/clusters/HDP/configuratons/service_config_versions'
but its not return any info
This format should work:
http://{HOSTNAME}:{PORT}/api/v1/stacks/HDP/versions/{STACKVERSION}/services?fields=StackServices/service_version
So for your example:
curl -k -u admin:admin -H 'X-Requested-By:admin' -X GET 'http://localhost:8080/api/v1/stacks/HDP/versions/2.6/services?fields=StackServices/service_version'

How do I Add User or Edit a Password on Solr 6.6 on Windows for basic authentication plugin using PowerShell's invoke-webrequest command?
Reference: http://lucene.apache.org/solr/guide/6_6/basic-authentication-plugin.html#BasicAuthenticationPlugin-AddaUserorEditaPassword
thanks
Used Curl for Windows as recommended by #MatsLindh
curl --basic --user solrAdmin:adminPassword
--url http://<server>:8983/solr/admin/authentication
--header 'Content-type:application/json'
--data "{'set-user':{'user1':'password1','user2':'password2'}}"
Curl for Windows downloaded at https://curl.haxx.se/dlwiz/?type=bin
Initially, I had a few errors and I had to switch the double and single quotes in the data/body from the example provided on Solr 6.6 documentation (link in question).
after adding new parameter and value to the ambari cluster , we need to restart the service to take affect
from ambari GUI restart the service is required , and we can see that because restart button is colored with orange
so my question is
we need API command that restart only the services that restart is required?
in order to restart all relevant services ( that need's restart ) the following syntax is the answer
curl -u admin:admin -H "X-Requested-By: ambari" -X POST -d '{"RequestInfo":{"command":"RESTART","context":"Restart all required services","operation_level":"host_component"},"Requests/resource_filters":[{"hosts_predicate":"HostRoles/stale_configs=true"}]}' http://amb25101.example.com:8080/api/v1/clusters/plain_ambari/requests
I have installed knox server and done all the steps mentioned on hortonworks site.
When i ran the below command on the sandbox , it gives me the proper output.
curl http://sandbox:50070/webhdfs/v1?op=GETHOMEDIRECTORY
Now i have another VM running fedora . I am assuming it as external client and trying to do external access but getting no output:-
curl -k https://<sandbox-ip>:8443/gateway/sandbox/webhdfs/v1?op=GETHOMEDIRECTORY
Can someone point me whats wrong with my settings.
Not sure about your topology but if you are using the default one (sandbox) you probably need to add basic auth e.g.
curl -k -u guest:guest-password -X GET https://<sandbox- ip>:8443/gateway/sandbox/webhdfs/v1?op=GETHOMEDIRECTORY
Also check the logs at
<knox_install>/logs/gateway.log
They should tell you more about what went wrong.
Good luck !
I have added Ranger Service (Ranger Admin Server, Ranger Usersync, and Ranger KMS) to the existing Ambari 2.3 cluster (4 nodes), running on the Ubuntu 14.04 Servers. All services are on the Master Node. However, it doesn't installed correctly and now it shows 'Install Failed' on the left hand side column of available Services on the Main Ambari page, and I believe this is what puting the Master node down. I can't find any option available to Delete the Service on the Ambari Web UI. I followed this tutorial, but without success. Every time I try to delete whole service with the following command
curl -u admin:admin -X DELETE http://AMBARI_SERVER_HOST:8080/api/v1/clusters/c1/services/SERVICENAME it ends up with an error: "400"... something...
you need to add "X-Requested-By ... "
So my commands according to our system was:
curl -u admin:admin -X "X-Requested-By: ambari" DELETE http://localhost:8080/api/v1/clusters/cluster1/services/ranger
Also I've tried:
curl -u admin:admin -X "X-Requested-By: ambari" DELETE http://localhost:8080/api/v1/clusters/cluster1/services/rangeradmin
And finally:
curl -u admin:admin -X "X-Requested-By: ambari" DELETE http://localhost:8080/api/v1/clusters/cluster1/services/RangerAdmin
My thoughts is that as far as these services were not installed properly, the system can't see them. Or maybe some other issues..
However, I still cannot figure out what the actual command is, and is it possible at all to remove the service?!? I know I can hide this issue, with the 'Turn On Maintanace Mode' as option, and in that case Master Node will run as normal, but I want to completelly get rid of this Service, as I don't need it anymore. Any help appriciated, as I spent half a day trying to remove it, with no success.
sorted. if anyone interesting to delete Ambari services (in my case it was a RANGER) from the command line, run the following:
// get the service
curl -u admin:admin -X GET http://HOST_NAME:8080/api/v1/clusters/CLUSTER_NAME/services/RANGER
// stop the service
curl -u admin:admin -H 'X-Requested-By: ambari' -X PUT -d '{"RequestInfo":{"context":"Stop Service"},"Body":{"ServiceInfo":{"state":"INSTALLED"}}}' http://HOST_NAME:8080/api/v1/clusters/CLUSTER_NAME/services/RANGER
// delete the service
curl -u admin:admin -H 'X-Requested-By: ambari' -X DELETE http://HOST_NAME:8080/api/v1/clusters/CLUSTER_NAME/services/RANGER
P.S. Simply put your hostname instead of HOST_NAME and your cluster name instead CLUSTER_NAME
Hope it helps anyone with the same issues.

You can use cygwin with the curl extension installed or you can - for example - to manualy querying.
You can also install the plugin head for elasticsearch wich permit you to test your index, more information about head plugin here:
