[GitHub] metron pull request #1244: Fix issue with idempotency of Elasticsearch MPack...
GitHub user nickwallen opened a pull request:

Fix issue with idempotency of Elasticsearch MPack installation step
When re-provisioning the development environment, the "Install Elasticsearch MPack on Ambari Host" step will fail. This step needs to be idempotent so it succeeds when re-provisioned.
## Testing
1. Spin-up a development environment.
```
cd metron-deployment/development/centos6
vagrant up
```
1. Re-provision the same environment after the fist completes.
```
vagrant --ansible-skip-tags="build,sensors" provision
```
1. If the re-provision makes it past the "Install Elasticsearch MPack on Ambari Host" step, the change is good.

Hey @nickwallen , I am seeing an error at the `ambari_gather_facts : Ask Ambari: core_site_tag` step when trying to validate the fix.
1. Re-created the problem first by:
a) Running `vagrant up`
b) Then attempting `vagrant provision` again
c) Noticed the following error:
```

2. Destroyed the VM, applied the fix and
a) Running `vagrant up`
b) Then ran `vagrant --ansible-skip-tags="build,sensors" provision` after which I am seeing the below error:

Hey @nickwallen , I am seeing an error at the `ambari_gather_facts : Ask Ambari: core_site_tag` step when trying to validate the fix.
1. Re-created the problem first by:
a) Running `vagrant up`
b) Then attempting `vagrant provision` again
c) Noticed the following error:
```
TASK [ambari_master : Install Elasticsearch MPack on Ambari Host] **************
fatal: [node1]: FAILED! => {"changed": true, "cmd": "ambari-server install-mpack --mpack=/tmp/elasticsearch_mpack-0.6.1.0.tar.gz", "delta": "0:00:00.433435", "end": "2018-10-21 18:12:29.939320", "msg": "non-zero return code", "rc": 255, "start": "2018-10-21 18:12:29.505885", "stderr": "", "stderr_lines": [], "stdout": "Using python /usr/bin/python\nInstalling management pack\nERROR: Management pack elasticsearch-ambari.mpack-5.6.2 already installed!\nERROR: Exiting with exit code -1. \nREASON: Management pack elasticsearch-ambari.mpack-5.6.2 already installed!", "stdout_lines": ["Using python /usr/bin/python", "Installing management pack", "ERROR: Management pack elasticsearch-ambari.mpack-5.6.2 already installed!", "ERROR: Exiting with exit code -1.

to retry, use: --limit @/Users/asubramanian/Desktop/Metron/anand-metron-fork/metron-latest/metron/metron-deployment/development/centos6/ansible/playbook.retry
```
2. Destroyed the VM, applied the fix and
a) Running `vagrant up`
b) Then ran `vagrant --ansible-skip-tags="build,sensors" provision` after which I am seeing the below error:
```

Am I missing something?
