[PR] MAPREDUCE-7539. JobHistoryServer API fails to serve aggregated logs d… [hadoop]

ferdelyi opened a new pull request, #8555:
URL: https://github.com/apache/hadoop/pull/8555

   …ue to uuid mismatch
   
   Fix IFile aggregated log reads after HADOOP-15984 singleton web services.
   
   HADOOP-15984 made HsWebServices a singleton, so LogAggregationIndexedFileController is reused across /ws/v1/history/aggregatedlogs requests. IFile log meta reads validated UUIDs against a cached instance field from the first application, causing aggregated logs for other apps to fail until JHS restart.
   
   Derive the expected UUID from the application being read. Add regression tests and call postWrite() in test log upload helpers so IFile metadata is written.
