Elliott Clark commented on HADOOP-8336:
---------------------------------------
We were seeing this when reading 64k blocks. So the file was opened. Then read 64k. Then
seek to 128k then try and read.
I'll try and come back to this with a test or more detailed info in a little bit.
> LocalFileSystem Does not seek to the correct location when Checksumming is off.

> Hbase was seeing an issue when trying to read data from a local filesystem instance with
setVerifyChecksum(false). On debugging into it, the seek on the file was seeking to the checksum
block index, but since checksumming was off that was the incorrect location.
