Vinod K V commented on MAPREDUCE-1978:
--------------------------------------

The patch looks good to me too. I'd be happy if the test can be modified to do away with all the find/awk kludge - for e.g. {{createHistoryLogsHierarchy()}} knows the list of files being created and so can return the same; for the flat list, {{File.listFiles()}} should suffice.

The test results were posted a while ago, please run them once more after the test changes just to be sure.

> Currently, {{TraceBuilder}} assumes that the input is either jobhistory files or a folders containing jobhistory files directly underneath the specified folder. There could be a use cases where the input folder could contain sub-folders containing jobhistory files. Rumen should support such input folders.
