Ambari-Server 1.7.0-ea issues

[keyki]

Hi,

The Ambari repository points to a nightly build thus it's not stable. It is supposed to be a tryout version until it is not officially released we have no control over what is published. I suggest you to use the 1.6 version. 1.7 will come late november.

Hi,

Unfortunately the project I'm working with requires 1.7 - hence my excitement at finding the blog entry. Do you have any recommendations on where to begin looking, in order to try to figure this out? As in... log locations to try to see initially, etc.

Thanks for the response!

Hi,

Could you please login to the UI to see which service's installation failed? I'll try to fix/update the container.

In the meanwhile you can look around on the wiki https://cwiki.apache.org/confluence/display/AMBARI/Ambari they usually post the right repositories to use there.

Of course, see the below screenshot for overall service failures. If you need/want further detail please let me know! I'll dig around that wiki and see if I can find anything.

Here is one exception seen from App Timeline service:

I opened a JIRA issue for the timeline server https://issues.apache.org/jira/browse/AMBARI-7578 but it should be fixed by now. I'll take a look at it.

[cyon666]

Thanks. As I said, I've done nothing out of what was noted in the blog entry. If I can provide anything else, please just let me know (as in any log files from my side, any other attempts, etc).

We can reproduce these - nevertheless if we'll need your logs, etc will let you know. By any chance - if it's for public domain - can you let us know what are the 1.7 features you are building on - maybe there is another alternative/workaround in the meanwhile.

[cyon666]

The stack framework matured in 1.7, which is the most important feature for us. 1.5 introduced support for custom stacks, and 1.6 carried it over but we continuously had problems in both versions. Obtaining ambari 1.7 stand-alone and working with that seemed much more promising than its predecessors in regards to this need. 1.7 is more stable for this use, and while still not perfect is fitting our needs well.

As a result, blueprint support for custom stacks is also important for us. HDP 2.2 plays a vital role with its support for Kafka as well.

That's the best overall info I can provide at the moment. Sorry for the delay in a response.

Hi Randy,

Unless you need the timeline server you can get rid of it from the blueprint and install a cluster without it. You can use the same ambari-functions:
amb-start-cluster 2
amb-shell
blueprint add --url https://raw.githubusercontent.com/sequenceiq/docker-ambari/1.7.0-ea/multi-node.json
cluster build --blueprint multi-node-hdfs-yarn
cluster autoAssign
cluster create

Stripping out the culprit service did allow for a full deployment of Ambari 1.7-ea. I appreciate the responses from both of you. Keyki, thanks for taking the extra step to help me move forward.

I really appreciate ya'lls efforts!

[cyon666]

Closing as a result of the work-around. Looking forward to the "official" release later this month / year.

1.7.0 is out, feel free to use it anyway you want. docker pull sequenceiq/ambari:1.7.0
