Jason Lowe commented on YARN-6905:
----------------------------------

These tests are failing because they are mixing and matching very different 
versions of Hadoop jars.  IIUC the Hadoop project does not make any binary 
compatibility claims when mixing different versions of jars that are 
distributed as part of Hadoop itself.  To me this looks like an invalid setup.

> Multiple test failures due to FastNumberFormat
