Description

==== First ====
Currently in Metron Mpack es.ip in Metron configuration is set to: es_url.

Which is incorrect and will fail, instead it should be replaced with:
"es.ip": "<elasticsearch_master_hostname>",
"es.port": "9300",

But I do not know how to get elasticsearch_master_hostname. Also, value of es.port seems like can be defaulted to es_binary_port or even omitted as it is already specified in es_binary_port.

This should be chanted in:
https://github.com/apache/incubator-metron/blob/master/metron-deployment/packaging/ambari/metron-mpack/src/main/resources/common-services/METRON/CURRENT/configuration/metron-env.xml
On line 208.

On lines 93 and 95 symbols "/" is forgotten. e.g:
ES_JAVA_OPTS="-verbose:gc -Xloggc:log_dir/elasticsearch_gc.log -XX:-CMSConcurrentMTEnabled
should be:
ES_JAVA_OPTS="-verbose:gc -Xloggc:log_dir/elasticsearch_gc.log -XX:-CMSConcurrentMTEnabled

After ES install it will fail to start with error"

Likely root cause: java.nio.file.AccessDeniedException: /etc/elasticsearch/scripts

The reason for the is root permission on these files:

 # ls -la /etc/elasticsearch
...
-rwxr-x---.   1 root          elasticsearch  2571 May 12 09:24 logging.yml
drwxr-x---.   2 root          elasticsearch  4096 May 17 11:49 scripts

I was not able to trace down origin of these files, so do not know how to fix it.
