Make URL encoding consistent
----------------------------
Key: HADOOP-7527
URL: https://issues.apache.org/jira/browse/HADOOP-7527
Project: Hadoop Common
Issue Type: Improvement
Affects Versions: 0.23.0
Reporter: Eli Collins
URL encoding is currently handled in at least 4 different ways. We should make
these consistent:
# Parameters are encoded when a URI object is created
# HttpServlet uses RequestQuoter to html escape parameter names and values
# StringEscapeUtils is used to escape parameters in ReconfigurationServlet and
DatanodeJspHelper
# URLEncoder and URLDecoder are used in multiple places
We should also be consistent about how we pass file names in URLs, some times
they're passed in the path segment, sometimes they're passed in the query
fragment as parameters.
