Kibana hangs when too many fields in an index with no information around this

[gmoskovicz]

I created a index with a custom script with around 50k fields for a specific type and index. The size of the mapping was around 10MB (which is abnormal for just one index, i know).

When i try to refresh the fields, or go to Discovery, Kibana hangs with no information.

Look related to this thread: https://forum.jquery.com/topic/map-throws-maximum-call-stack-size-exceeded-exception

While this amount of fields is abnormal, we should think about raising a custom exception or a message around that too many fields are not allowed. This clearly is an issue around the mapping for this types, but we need a way to control this.
