hi all,   i have a problem. I have one table in Impala, partition by year, month, day, name of the load file.  Example     /user/hive/warehouse/table/year=2015/month=01/day=01/nameloadfile1/file.parq /user/hive/warehouse/table/year=2015/month=01/day=01/nameloadfile1/file2.parq /user/hive/warehouse/table/year=2015/month=01/day=01/nameloadfile1/file3.parq   the size of the file is very smaller (low MB). I would want combine all files in one.   /user/hive/warehouse/table/year=2015/month=01/day=01/nameloadfile1/combineFiles.parq   Someone have any idea for that.   Best regards     ... View more
