This is a know issue with the latest update of Lightroom version CC2015.2.1 and our engineering team is currently working to address the issue.
The workaround for now would be to roll back to Lightroom CC2015.1.1

Good to hear that the problem with exporting will be addressed. It has been a couple of weeks, is there anything you can tell us as to when this issue will be fixed? I have a lot of photos from a big safari shoot to upload to my website and would greatly prefer to upload them in a batch as I normally do rather than one by one. I'd prefer not to downgrade because I do use the targeted dehaze filter quite a bit.
Adobe generally does not publish any details about the next release. Many, many people have encountered serious problems with CC 2015.2.1 and reverted back to 2015.1.1: http://www.lightroomqueen.com/how-do-i-roll-back-to-lightroom-2015-1-1-or-lightroom-6-1-1/. The Dehaze feature is present in 23015.1.1.
Thanks, johnrellis. I know that the dehaze is present in 2015.1.1, and I may still revert to that version. However, I do like the inclusion of dehaze in the targeted filters like the radial filter and the brush, and that didn't happen until 2015.2.1. I'll check out the link you referenced.I also recall that in mid-August when I uploaded a lot of files to my website on Zenfolio, I had problems with Jeff Friedl's plugin when I tried to export several files to the website at once. So I am not sure that the same problem didn't already exist in 2015.1.1, at least if you used a plugin to export your files.

Got it. The more common name for that is "local adjustment". Yup, you're stuck if you really want local dehaze a version that is stable :-<

Versions of 2015 prior to 2015.1.1 had some export problems. But I've published several hundred photos to Zenfolio with Friedl's plugin without issue, and I haven't seen any other reports about such problems with 2015.1.1.
