Read the logs in batches during log splitting to avoid OOME
-----------------------------------------------------------
Key: HBASE-1430
URL: https://issues.apache.org/jira/browse/HBASE-1430
Project: Hadoop HBase
Issue Type: Improvement
Reporter: Jean-Daniel Cryans
Assignee: Jean-Daniel Cryans
Priority: Blocker
Fix For: 0.20.0, 0.19.3
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.
