Luke Lu commented on MAPREDUCE-1442:
------------------------------------
Amarsri, my test case for the old parser exploits details of the old file
format and weaknesses of Java's backtracking NFA regex implementation. The new
implementation in trunk uses the standard json format and a mature json parser
(jackson) with about 700 tests. It'll be counterproductive for me to add any
tests to have any material impact to the test coverage of the new parser.
