Moving historyserver to another instance using curl command

0 votes
Hi Team,

I am trying to move mapreduce history server to another instance using curl command .

curl -u admin:admin -H "X-Requested-By:ambari" -i -X POST -d  '{ "Credential" : { "principal" : "<orincipal", "key" : "<keyadmin>", "type" : "persisted" } }' '{RequestInfo":{"context":"Install MapReduce "}, "Body":{"HostRoles":{"state":"INSTALLED"}}}' 'http://node1:8080/api/v1/clusters/<clustername>/services/MAPREDUCE2'.

Unfortunately I am getting below error::

curl: (3) [globbing] nested braces not supported at pos 16

HTTP/1.1 400 Bad Request

X-Frame-Options: DENY

X-XSS-Protection: 1; mode=block

X-Content-Type-Options: nosniff

Cache-Control: no-store

Pragma: no-cache

Set-Cookie: AMBARISESSIONID=1djqii0d05hby3zpi0xa3v9l8;Path=/;HttpOnly

Expires: Thu, 01 Jan 1970 00:00:00 GMT

User: admin

Content-Type: text/plain

Content-Length: 195

{

  "status" : 400,

  "message" : "The properties [Credential/key, Credential/type, Credential/principal] specified in the request or predicate are not supported for the resource type Service."

}

Where  I am going wrong .

Hi@Shilpa,

You have double quotes inside a single quote. I think this is the issue. Try to correct the syntax. Use single quotes inside double-quotes.

"{ 'Credential' : { 'principal' : 'orincipal', 'key' : '', 'type' : 'persisted' } " still it dint wrk
Hi@Shilpa,

Check your command. You have double quotes inside a single quote.

 '{ "Credential" : { "principal" : "<orincipal", "key" : "<keyadmin>", "type" : "persisted" } }' '{RequestInfo":{"context":"Install MapReduce "}, "Body":{"HostRoles":{"state":"INSTALLED"}}}'
THANKS .

But still same issue "{ "Credential" : { "principal" : "", "key" : "", "type" : "temporary" } }' '{"RequestInfo":{"context":"Install MapReduce "}, "Body":{"HostRoles":{"state":"INSTALLED"}}}'"

But I could install MR histry server without proving credential ,Its sounds strange .Followed this doc "https://cwiki.apache.org/confluence/display/AMBARI/Move+Mapreduce2+History+Server"
Hi@Shilpa,

Can you share your modified command?
