Hi, I don't think Trafodion requires YARN for most activity.
For Hive table access, Trafodion uses Hive metadata access Java API and libhdfs to actually scan the data file. Therefore YARN is not needed for Hive access. YARN is not needed for native Hbase or Trafodion table access too. YARN is needed for backup/restore, since the HBase exportSnapshot class Trafodion calls, used MapReduce to copy large snapshot files to/from the backup location. YARN is also needed for developer regressions as some vanilla Hive commands are executed during the regression run. For the last 2 lines I think both MRv1 and MRv2 is supported.
