Eli Collins updated HADOOP-7089:

Per Allen's suggestion, updated the patch to add a comment indicating -P requires bash built-ins
or POSIX:2001 cd and pwd.

> The link resolution logic in bin/hadoop-config.sh fails when when executed via a symlink,
from the root directory.  We can replace this logic with cd -P and pwd -P, which should be
portable across Linux, Solaris, BSD, and OSX.
