Luke Lu updated MAPREDUCE-1442:
-------------------------------
Attachment: mr-1442-y20s-v1.patch
Patch for y20s branch (probably works with generic 0.20.x as well): one line
change to add possessive qualifiers to mutually exclusive patterns to avoid
useless backtracking and hence stack overflow for values with many escaped
characters.
> StackOverflowError when JobHistory parses a really long line
