-------------------------------------
Summary: HFileContext defaults can lead to inconsistency with
expectations of HFile block header sizing between readers and writers
Key: HBASE-9596
URL: https://issues.apache.org/jira/browse/HBASE-9596
Project: HBase
Issue Type: Sub-task
Reporter: Andrew Purtell
Assignee: ramkrishna.s.vasudevan
Priority: Minor
HFileContext defaults can lead to inconsistency with expectations of HFile
block header sizing between readers and writers. In HConstants the default
block header is now the one including checksum, but by default HFileContext has
useHBaseChecksum set to false. If creating readers and writers directly rather
than going through HFile, you can end up with a writer producing block headers
including the checksum and a reader expecting headers without, leading to sad
results. Minor issue but worth looking at to avoid surprises.
