> For push based shuffle metrics, when writting out the event to log file, the field name is "Push Based Shuffle", in [https://github.com/apache/spark/blob/master/core/src/main/scala/org/apache/spark/util/JsonProtocol.scala#L548]
> But when parsing it out in SHS, the expected field name is "Shuffle Push Read Metrics", as shown [https://github.com/apache/spark/blob/master/core/src/main/scala/org/apache/spark/util/JsonProtocol.scala#L1264]
> This mismatch makes all the push shuffle metrics 0 from SHS rest calls.
