Todd Lipcon commented on HADOOP-3205:
-------------------------------------
bq. -1 tests included. The patch doesn't appear to include any new or modified
tests.
I believe this code path to be well exercised by existing tests (almost all the
tests that do file IO go through this path and exercise it pretty well - note
that existing tests failed when there were bugs in prior versions of the patch)
> Read multiple chunks directly from FSInputChecker subclass into user buffers

> Implementations of FSInputChecker and FSOutputSummer like DFS do not have
> access to full user buffer. At any time DFS can access only up to 512 bytes
> even though user usually reads with a much larger buffer (often controlled by
> io.file.buffer.size). This requires implementations to double buffer data if
> an implementation wants to read or write larger chunks of data from
> underlying storage.
> We could separate changes for FSInputChecker and FSOutputSummer into two
> separate jiras.
