Tsz Wo (Nicholas), SZE commented on HADOOP-3854:
------------------------------------------------
Here is an example showing how to configure filters:
- SampleInitializer.java: It implements HttpServerInitializer.
- LoggingFilter.java: A very simple filter which does logging.
- Specify SampleInitializer in conf as below
{code}
<property>
<name>hadoop.http.initializer</name>
<value>org.apache.hadoop.http.SampleInitializer</value>
<description>A class implementing
org.apache.hadoop.http.HttpServerInitializer for customized initialization of
HttpServer objects.</description>
</property>
{code}
Then, a message will be added to log for all http requests/responses.
> org.apache.hadoop.http.HttpServer should support user configurable filter
