hfile meta block handling bugs
------------------------------
Key: HBASE-1245
URL: https://issues.apache.org/jira/browse/HBASE-1245
Project: Hadoop HBase
Issue Type: Bug
Affects Versions: 0.20.0
Environment: all
Reporter: ryan rawson
Fix For: 0.20.0
HFile doesn't handle 'get meta block' when there are no meta blocks. It throws
an unhelpful exception "meta index not loaded", which is not the case. No meta
blocks = no meta index. It should return null instead.
Additionally, hfile doesn't even get all meta names properly, due to the
incorrect use of the file's comparator, instead of using just a bytes
comparator in the index. This is manifested by NPEs in some tests.
