Jean-Daniel Cryans updated HBASE-1058:
--------------------------------------
Attachment: hbase-1058.patch
I'm using this patch on a cluster of old machines to get the whole wikipedia
articles dump in a table. Not using it, I saw a store with 150+ store files in
it while it was trying to compact the first 20 or so (which had the machine to
start swapping, hell broke loose, etc).
Basically it does a check after we get the updatesLock write lock to make sure
there is not a single store with more than hbase.hregion.memcache.store.maximum
files (default is 6) and if there is, sleep 500ms until it's resolved.
This patch was made against 0.19 branch.
