Description

Lucene.zones.apache.org and I assume hudson.zones limit the number of file handles to 256. TestMiniMRDFSSort runs better with more file handles. (I set it to 10000 in my testing, but a smaller value is probably ok.) I suggest the QA scripts increase the ulimit before running the unit tests with "ulimit -n 10000".
