@Aravindan Vijayan yes, Ive done that part. Its been working since the upgrade. Maybe the documentation should be updated so it is not confusing. I remember running into sth similar whne upgrading to 2.4 last year. Speaking of documentation, it should be more obvious with regards to grafana when upgrading from 2.5 to 2.6, since in 2.5 Grafana is already a part of the stack, but the upgrade docs consider it as a service that must be installed and not how to upgrade it (or if there is an upgrade). ...

I may be teaching wrong religion and not helping you directly here: I went away from Zeppelin in Ambari and installed it on a client manually - not a biggie. Have full control over it now. Good luck. ... View more

So the answer to my question would be: File add_to_group.amb: { "MemberInfo/user_name":"user1", "MemberInfo/group_name":"group1" } curl -iv -u admin:admin -H "X-Requested-By: ambari" -X PUT -d @add_to_group.amb http://ambari-server:8080/api/v1/groups/group1/members This works! Thank you, @sbhat ... View more

@sbchat I had to unaccept the answer. What happens now is that the user is added, but the old users from the group are removed from it. Can you check if this behaviour occurs on your side as well? ... View more

@sbhat I ran what you recommended under adding user to a group and Im getting 405 Method not allowed. I tried with -X POST rather than PUT and Im getting this error: { "status" : 400, "message" : "The properties [MemberInfo/user_name, MemberInfo/group_name] specified in the request or predicate are not supported for the resource type Group." * Connection #0 to host ambari-server left intact } so I updated the string by adding members/ in front of MemberInfo, like this: { "members/MemberInfo/user_name":"user1", "members/MemberInfo/group_name":"group1" } and the error is the same. Im using Ambari 2.2.2.0 if this has to do with anything. ... View more

@Jorge de la peña Jorge, next time you should quote the user you are talking to. Pure luck I saw your post. Thank for posting this, btw.

@Neeraj Sabharwal The way I have tested RZeppelin twice now is the following: I ran the RInterpreter and it worked fine. As soon as I try something on my own, I get this error. The second time I installed, I wanted to run your flights example and when I wanted to load the four libraries I already got this error message. btw, Im surprised your installation was successful without installing Cairo package. I had to install cairo package before running install install_github('IRkernel/repr'). If I run the following command in R: #list all installed packages and versions: ip <- as.data.frame(installed.packages()[,c(1,3:4)]) rownames(ip) <- NULL ip <- ip[is.na(ip$Priority),1:2,drop=FALSE] print(ip, row.names=FALSE) Packages and versions you mention in your git (plus Cairo): base64enc 0.1-3 Cairo 1.5-9 caret 6.0-64 devtools 1.10.0 dplyr 0.4.3 evaluate 0.8 repr 0.4 This is the list of all installed packages: r-installed-pkgs.txt My R version: > version _ platform x86_64-pc-linux-gnu arch x86_64 os linux-gnu system x86_64, linux-gnu status major 3 minor 2.3 year 2015 month 12 day 10 svn rev 69752 language R version.string R version 3.2.3 (2015-12-10) nickname Wooden Christmas-Tree ...

@Neeraj Sabharwal Ive set up Spark 1.6.0, installed sparkR environment, and built and started zeppelin with R interpreter. I managed to run the RInterpreter notebook.

@Neeraj Sabharwal No, the spark installation was done through Ambari. I installed, accepted all the defaults and ran the test examples from the TP website.Funny thing, when installing, you get to choose 1.4.2 version of spark, while 1.5.2 is installed. ... View more
