Matt Corgan commented on HBASE-5720: ------------------------------------ I've confirmed in some isolated test cases, and I'm running the test suite now. I think i have one more fix as well though where .92 files cannot get encoded from disk to memory because the .92 files have no encoderId. Doesn't break anything but skips the desired encoding. I'll add that fix to this patch since they're both related to .92 compatibility. > HFileDataBlockEncoderImpl uses wrong header size when reading HFiles with no > checksums > -------------------------------------------------------------------------------------- > > Key: HBASE-5720 > URL: https://issues.apache.org/jira/browse/HBASE-5720 > Project: HBase > Issue Type: Bug > Components: io, regionserver > Affects Versions: 0.94.0 > Reporter: Matt Corgan > Priority: Blocker > Fix For: 0.94.0 > > Attachments: HBASE-5720-v1.patch > > > When reading a .92 HFile without checksums, encoding it, and storing in the > block cache, the HFileDataBlockEncoderImpl always allocates a dummy header > appropriate for checksums even though there are none. This corrupts the > byte[]. > Attaching a patch that allocates a DUMMY_HEADER_NO_CHECKSUM in that case > which I think is the desired behavior. -- This message is automatically generated by JIRA.
