I had to remove them to reclaim space, but I preserved one on snapshot1007 in /mnt/data/logs/dumpwikidatajson-wikidata-20171120-all-1.log and it's full of json output. Adding @hoo because he's working on these.

The command that wrote the above log was this:

php5 /srv/mediawiki/multiversion/MWScript.php extensions/Wikidata/extensions/Wikibase/repo/maintenance/dumpJson.php --wiki wikidatawiki --shard 1 --sharding-factor 6 --batch-size 1000 --snippet 2 --no-cache

Contents of the output files in /mnt/data/xmldatadumps/temp:

@hoo if you don't see anything else amiss, feel free to start the job manually at any time. I'll clean up that temp log file I left laying around then, too.
