Enter this in the Pig query editor:
fs -mkdir /tmp/foo
fs -touchz /tmp/foo/bar
fs -rm /tmp/foo/*
fs -touchz /tmp/comment
Actual behavior: Pig removes the files /tmp/foo/* (being /tmp/foo/bar only at the time), then creates /tmp/comment, then fails on */ being a syntax error.
Hue's Pig editor suggests: Pig will try to remove the file /tmp/foo, and then there's some comment enclosed by /* */.
Apparently /* doesn't start a comment if preceded by a letter-like symbol (and presumably something similar might go for */ as well). Hue should highlight the syntax accordingly.
