Pallavi Rao commented on FALCON-1308:
-------------------------------------
The error that gets thrown:
{code}
java.lang.IllegalArgumentException: opt contains illegal character value '.'
at
org.apache.commons.cli.OptionValidator.validateOption(OptionValidator.java:73)
at org.apache.commons.cli.Option.<init>(Option.java:123)
at org.apache.commons.cli.Option.<init>(Option.java:105)
{code}
Option uses an OptionValidator that rejects an option name if it has '.' in it.
> Allow namespace-ing of custom properties in the entity specification

> Project: Falcon
> Issue Type: Improvement
> Components: common
> Reporter: Pallavi Rao
>
> There are some Falcon system properties that are supplied as custom
> properties in the Entity definition. Ideally, we should prefix these with
> "falcon.system" to distinguish them from user-supplied properties.
> Currently, we cannot have property names that have '.' in them as the Commons
> CLI (OptionValidator) rejects such names.
