> TEZ-2581 changed/renamed some of HistoryEventType. This causes parser to throw exception when trying to parse 0.7.x ATS data with 0.8.x parser.
> {noformat}
>  Exception in thread "main" java.lang.IllegalArgumentException: No enum constant org.apache.tez.dag.history.HistoryEventType.VERTEX_PARALLELISM_UPDATED
>        at java.lang.Enum.valueOf(Enum.java:238)
>        at org.apache.tez.dag.history.HistoryEventType.valueOf(HistoryEventType.java:21)
>        at org.apache.tez.history.parser.datamodel.VertexInfo.<init>(VertexInfo.java:117)

>        at org.apache.tez.history.parser.ATSFileParser.getDAGData(ATSFileParser.java:70)
> {noformat}
> Long term fix is to have versioning support (TEZ-3179) in ATS data.
