how to trace blueprint installation and find errors during blueprint installation

we are installing new ambari - cluster with the following Kits:

  1. HDP-2.6.3.0-centos7-rpm.tar.gz
  2. ambari-2.6.0.0-centos7.tar.gz

blueprint installation failed ,

we try to capture the ambari-server.log , but not found usful info about why blueprint failed

please advice what is the best approach to trace blueprint installation ?

which log indicate the blueprint installation on the highest level ? or maybe some API that can put light why blueprint failed ?

@Michael Bronson There are a different possible reasons why the install failed. Will list out a couple of them here

1. Invalid configs in topology/ Invalid topology: In this scenario, your Ambari background operations will show Logical request in Pending status. Ambari-server.log will have the info about which configuration had invalid values

2. Service install/start failures: Details of failures will be available in Ambari background operations window. You can also use Ambari API to figure out what failed. And individual service logs usually have more details about the failure.

E.g

http://<AMBARI_HOST>:8080/api/v1/clusters/cl1/requests?to=end&page_size=100&fields=tasks/*&tasks/Tas...

Hope this helps!

@kramakrishnan this i

installation with the new kit is exactly as the previous kits , and previous kits installed more then 100 times without problem , so my qiuastion is dose this new version required some addtiknal configuration?
