Description

I am a beginner of apache knox. When I use knox to proxy my sparkhistoryui, I meet this problem.

 <a href="/history/application_1505879554093_0036/stages/stage?id=0&amp;attempt=0" class="name-link">

Some query parameters in the response body of the spark history ui contain a

&

org.apache.hadoop.gateway.util.urltemplate.Parser#consumeQueryToken does not handle this case

StringTokenizer tokenizer = new StringTokenizer( token, "?&" );
      while( tokenizer.hasMoreTokens() ) {
        consumeQuerySegment( builder, tokenizer.nextToken() );
      }

so,I changed the code block as bellows

String[] tokens = token.split("(&|\\?|&)");
      if (tokens != null){
        for (String nextToken : tokens){
          consumeQuerySegment(builder,nextToken);
        }
      }
