> httpclient-4.0.1.jar used by AMS collector does not have method
> URLEncodedUtils.parse (final URI uri, final String encoding). This will cause
> the metrics not to be populated and the collector log to be flooded with the
> following exception when when the Ambari-Metrics service is in distributed
> mode and the user configures http authentication filter without enabling
> Kerberos:

> Steps to reproduce:
> 1. install a cluster with default from Ambari Web UI
> 2. configure Ambari Metrics service in distributed mode
> 3. Add the following properties in Custom core-site from Ambari Web UI:
> 1).
> hadoop.http.authentication.signature.secret.file=/etc/security/http_secret
> 2).
> hadoop.http.filter.initializers=org.apache.hadoop.security.AuthenticationFilterInitialize
> 4. create /etc/security/http_secret text file on each node
> 5. restart HDFS, YARN, Mapreduce2, HBase, Kafka, and Ambari Metrics service
> 6. Metrics on dashboard and HDFS, YARN, HBase, Kafka, and Amabari Metrics
> will show No Data Available.
