Description

This is from the review of HADOOP-14910
There is also other place usage of decodeComponent(param(CreateFlagParam.NAME), StandardCharsets.UTF_8);
In ParameterParser.java Line 147-148:
String cf = decodeComponent(param(CreateFlagParam.NAME), StandardCharsets.UTF_8);

Use QueryStringDecoder from netty here too and cleanup the decodeComponent. Actually this is added for netty issue only.
