[jira] [Created] (HBASE-16644) Errors when reading legit HFile'
Trailer on branch 1.3
Mikhail Antonov created HBASE-16644:
---------------------------------------
Summary: Errors when reading legit HFile' Trailer on branch 1.3
Key: HBASE-16644
URL: https://issues.apache.org/jira/browse/HBASE-16644
Project: HBase
Issue Type: Bug
Components: HFile
Affects Versions: 1.3.0, 1.4.0
Reporter: Mikhail Antonov
Assignee: Mikhail Antonov
Fix For: 1.3.0
There seems to be a regression in branch 1.3 where we can't read HFile trailer(getting "CorruptHFileException: Problem reading HFile Trailer") on some HFiles that could be successfully read on 1.2.
I've seen this error manifesting in two ways so far.

In my case this problem was reproducible by running `hbase hfile -m -f` command. There seem to be two changes in behavior introduced by HBASE-15477 (cc [~stack]).
One is that HFileBlock#getOnDiskSizeWithHeader always assumes that checksum verification is true (this behavior results in onDiskSizeWithHeader being calculated differently in 1.2 and 1.3 for some cases).
Second is that in HFileBlock constructor we always attempt to retrive checksum-related fields from the header even if no checksum verification is going on.
Attached is the patch which when applied allows 1.3 to read again the same HFiles.
