Applied the patch locally and tested with https://github.com/apache/hadoop/blob/trunk/hadoop-common-project/hadoop-common/src/main/bin/hadoop-functions.sh

$ python shelldocs/src/main/python/shelldocs.py --lint -i ~/git/github/hadoop/hadoop-common-project/hadoop-common/src/main/bin/hadoop-functions.sh -o out
ERROR:root:/Users/aajisaka/git/github/hadoop/hadoop-common-project/hadoop-common/src/main/bin/hadoop-functions.sh:2063: ERROR: function wait_process_to_die_or_timeout has no @replacerawtext

In the error message, @replacerawtext should be @replaceable.

Thanks!

I need to fix yetus' support too, since it won't know what to do about ERROR:root: as a prefix from logging. Although I should probably change the logging config really.

Verified the fix. Thank you!
