>
> Trunk and 0.94's HFile code has some fairly convoluted code for bypassing
> checksums and has mixed usage of runtime and io exceptions when error
> conditions arise. This jira would clean up the code to have better
> encapsulation and be more explicit about what kinds of exceptions are thrown
> and what they mean. (This was partially spurred by comments in reviews of
> HBASE-6586).
