------------------------------------------------
bq. Ah, so the motivating use-case is authentication. Should we address this
more directly then? With the proposed general mechanism, one might have to be
careful to disable it for shuffle transfers, and once configured, adding a
second filter for logging might be tricky. We currently really only want this
for authentication on user-facing web interfaces, right?
The filter mapping will solve the problem. We could exclude the web pages for
shuffle transfers. For adding a second filter, administrators could define a
filter chain via filter mapping.
> org.apache.hadoop.http.HttpServer should support user configurable filter

> Filters provide universal functions such as authentication, logging and

> individual site administrators could possibly configure filters for their web
