.META. is scanned once a minute (by default). If we see a split parent without daughters, wait some time for the daughters to show up and if still not present, add it (the info to add is in the splitA and splitB columns of parent). Even if the updates from regionserver go through at later date, it should not clash with what is already written. Above is a bit hacky but might help till we get all up on 0.21. I'm interested though in why the subsequent edits that added the daughter regions did not go through. Perhaps all handlers on the regionserver carrying .META. were occupied? Perhaps there was a block on taking on new writes because of lack of resources? Was this the same server that was running atop a HDFS that was suffering "too many open files"? > > 3. <<< Is there a public folder some place you can post them so I can pull > them.>>> > > Stack: perhaps I'll email it to you offline as a start.
