Github user mattf-horton commented on the issue: https://github.com/apache/incubator-metron/pull/455 @JonZeolla , thanks for the suggestions. Incorporated the SIG traps and better exit codes, as well as improvements to the 'find -exec' error catching logic. Also added 'set -e' and trap on ERR, and fixed an exit code in the fix-md-dialect.py script. Changes related to $() vs ``, and explicit declaration of array variables that are being initialized on first use, are valid alternative syntax, but my usages are equivalent. I consider the variants I used to be less cluttered, so I kept them. While I was at it, I also fixed METRON-717, splitting site.xml into a tracked template file and an untracked auto-generated portion, in git.
