Jean-Daniel Cryans updated HBASE-1430:
--------------------------------------
Attachment: hbase-1430-trunk-v1.patch
This patch makes it that we read, by default, in batches of 10 logs that we
then write right away. Was tested with 12 logs to split.
> Read the logs in batches during log splitting to avoid OOME

> During log splitting, in the worst case we can read 64 logs of 64MB which
> will surely bust any heap. Instead we should read the logs in batches of 5-10
> that we write right away.
