Chris Douglas reopened HADOOP-5307:
-----------------------------------
I reverted this for two procedural reasons:
# The patch never received a +1 or review
# Committing it all the way back to 0.19 is arguably appropriate, particularly
since it's an incompatible change
As for the content of the patch, adding a special value parsed as "null"
without escaping literal instances of it in a utility class is not good. The
use case is also unclear; where is this causing problems, configuration or
otherwise?
> Fix null value handling in StringUtils#arrayToString() and #getStrings()

> StringUtils#arrayToString() converts String array to a String of comma
> separated elements. If the String array includes null values, these are
> recovered as "null" (literal) from getStrings() method, which eventually
> causes configuration issues.
