Mars updated KNOX-1055:
-----------------------
    Description: 
I am a beginner of apache knox. When I use knox to proxy my sparkhistoryui, I 
meet this problem.

{noformat} <a 
href="/history/application_1505879554093_0036/stages/stage?id=0{color:#d04437}&amp;{code}{color}attempt=0"
 class="name-link">{noformat}

Some query parameters in the response body of the spark history ui contain a 
{code}&amp;{code}.
org.apache.hadoop.gateway.util.urltemplate.Parser#consumeQueryToken does not 
handle this case

{code:java}
StringTokenizer tokenizer = new StringTokenizer( token, "?&" );
      while( tokenizer.hasMoreTokens() ) {
        consumeQuerySegment( builder, tokenizer.nextToken() );
      }
{code}
so,I changed the code block as bellows
{code:java}
String[] tokens = token.split("(&amp;|\\?|&)");
      if (tokens != null){
        for (String nextToken : tokens){
          consumeQuerySegment(builder,nextToken);
        }
      }
{code}
