We have a '/api/v1/hdfs/{path}" endpoint that returns hdfs file contents.
That's the first call the client side makes. If that fails, it calls
'/api/v1/grok/get/statement' to get the pattern from the classpath. If that
fails it reports an error in the UI.
We could change '/api/v1/grok/get/statement' to check HDFS first and change
the client side logic to only call the grok endpoint. Does that make more
sense to you and do you think it's worth making that change?
