I took a swing through this, and generally this worked as expected. There
were a couple things in full dev that I'm not sure if they were preexisting or
not, just from unfamiliarity with how it worked before. If these things are
preexisting, it might be worth a follow on task to clean up.
1. If I try to create a new sensor without a name, I get an error "Unable
to save sensor config: Request method 'POST' not supported". We should be able
to give a more informative error, and really it should be on the fly like
validation like the Kafka topic name.
1. If a field is missing in a new sensor (e.g. topic or GROK statement), I
get "Unexpected end of JSON input". This makes me worry there's a structural
problem in the request, along with the lack of informative error.
1. The UI will happily let me try to recreate an existing sensor, and
apparently executes an update. I would expect it to refuse to let me override
an existing sensor. This includes on a running sensor, which is worrisome.
1. If we get a permission denied error while editing a parser (e.g. I tried
to edit squid and hit HDFS permissions), we throw a giant stack trace on the
screen.
