Is StringUtils.getTrimmedStringCollection gone?
I've got a Hadoop job that uses StringUtils.getTrimmedStringCollection. It
works when run on version 0.20.2, but now when I run it on a 0.20.203
cluster I get a No Such Method Exception for this call. When I go looking
through the 0.20.203 source I can't find it, so I assume it's been removed
but I don't see any documentation to this effect.
Has this call been removed? If so, is there something to take its place, or
should I just call String.trim() in a loop myself?

Looking at my setup again, I was running 0.20.2 with some patches, so one of
those patches probably picked up this method.

Great, that's good to know!
Nope, no other problem. Was probably just the fact that this isn't
_yet_, into any of the 0.20 stable branches.

For my purposes, the easiest thing to do is to just implement a string
trimmer in my own code. I don't need a backport. I just wanted to make sure
that this wasn't an indication of some other problem.

I believe you've run into some odd versioning issues. I took a look at
Apache Hadoop 0.20.2 release and I can't see this method.
It originated from https://issues.apache.org/jira/browse/HADOOP-2366
contributed by Michele, which was put into the higher 0.21 version.
0.20.203 is not something that'd be considered entirely 0.21+ yet IMO.
204 and 205 have more backports in them, but this particular fix
hasn't gone in yet.
You can perhaps request a backport of this ticket for the next
branch-0.20-security release (205/206) if you'd like to see it in
that. It might need some patch changes though, and it'd improve your
chances if you can post a backport too. Alternatively, you can look at
that patch, and implement a custom simple utility if that's the only
part of the larger fix you need.
P.s. These methods were also improved recently in
https://issues.apache.org/jira/browse/HADOOP-7300 by Todd.
