yes, i have a lot of small files. this is because i wanted to process hourly instead of daily.
i will be checking into whether this is the case, i now am re-running the process, and I see 332 files and directories, 231 blocks = 563 total. Heap Size is 119.88 MB / 910.25 MB (13%) Configured Capacity : 140.72 GB DFS Used : 6.63 MB Non DFS Used : 8.76 GB DFS Remaining : 131.95 GB DFS Used% : 0 % DFS Remaining% : 93.77 % I do not think this is the case, but I will be monitoring, and will see in half an hour. best regards, and thanks a bunch. -cam On Sat, Feb 12, 2011 at 3:00 AM, Christopher, Pat <patrick.christop...@hp.com> wrote: > If you're running with the defaults I think its around 20gb.
