Description
After upgrading httpc* in HADOOP-12767, ServletRequest can pass null value with getQueryString.
When PseudoAuthenticationHandler is used, NPE has been occurred.
We have encountered this exception in backporting to Hadoop 2.7.x, but it looks like it can occur later version Hadoops.
HTTP ERROR 500
Problem accessing /cluster. Reason:
INTERNAL_SERVER_ERROR
