 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

That patch looks like it should work. As I mention in an earlier comment, 
though, this strategy is brittle especially considering future changes. At the 
same time I cannot think of anything better offhand.

Let me move the trunk discussion into another jira and commit the 0.94 fix via 
this one. Everybody OK with that?

Matt Corgan commented on HBASE-5720:


Sounds fine to me. .94 is the important fix, while trunk has some time for more 
thorough testing, and things will probbaly get moved around even more by other 
features. 

Eventually it would be nice to isolate the code that deals with the fragile 
byte[]'s inside HFile blocks into separate src directories or projects. Then 
have that code implement interfaces similar to DataBlockEncoder.java. This 
would: 
* make it more testable, like a normal in-memory data structure without having 
to set up heavyweight testing environments 
* separate the encoding concerns from IO concerns. after the checksum happens, 
encoders/decoders should not even know what an IOException is 
* strongly discourage people from modifying anything in the codec packages 
without knowing what they're getting into 
* ensure the main project code only references the interfaces and not any codec 
internals (see if main project compiles without codecs in classpath) 
* make it easier for contributors to develop and profile the codecs without 
having to become experts in all aspects of hbase 
* help to simplify the main project. imagine if the gzip or snappy internals 
were sprinkled throughout the regionserver code. yikes.

+1 on commit to 0.94.  Open a blocker issue for fix on TRUNK.

@Matt Sounds great.  How do we do it?  The testable and individually maintained 
riffs I like.  When you say separate directories or projects, what you 
thinking?  It'd be a separate package or even a separate module if we ever get 
around to modularizing our build.  Regards separate project, where you think?

your comment, though). Do you want (and have time) to work out a patch for that?

Matt Corgan commented on HBASE-5720:


The ideal way to split code in my opinion would be to put it in multiple source 
directories in the same project, and then configure the build path to set up 
one-way visibility between source directories.  For example, the src/test/java 
folder would be able to see the src/main/java folder but not vice versa.  
Unfortunately, eclipse does not support that.  It has a global classpath per 
project.  Can't find the exact discussion, but similar to: 
https://bugs.eclipse.org/bugs/show_bug.cgi?id=224708.  

I can think of two alternatives:

1) Put multiple src directories in the main project, so everything is in that 
project's classpath.  Periodically have a human or something else remove 
non-core src directories from the classpath and see if that causes compilation 
errors in the main src.  I just tried removing the src/main/test directory from 
the classpath and was happy to see that the src/main/java folder still compiles.

2) A more heavy handed approach would be to create separate projects so you can 
actually enforce unidirectional classpath visibility.  That's how I've been 
developing HBASE-4676 which can be added to the main project as a separate jar. 
 Main project still compiles without it.  The downside of this is that having 
multiple projects is more configuration overhead, like you would probably need 
multiple svn repos.

I think moving towards #1 is a good start for core stuff while more exotic 
contributions could be made by submitting jars.  I'll try to nudge us in this 
direction with HBASE-4676, just wanted to make sure people agree that it's 
important =)

@Stack - yep. HBASE-4336 is pretty much what i'm getting at, but I don't know 
much about maven.  I think one-shot modularization of a large, fast moving 
project is dangerous/impossible.  A more practical approach is to decide on a 
couple modules and slowly start pulling things into them.  It could take years 
and never really be finished, but every time something is extracted to a module 
the main project becomes a little bit simpler.

 block cache, the HFileDataBlockEncoderImpl always allocates a dummy header 
 appropriate for checksums even though there are none.  This corrupts the

Sorry for attaching non-compiling patch.  Looking at this, its hard to get the 
a default header into the HFileBlockDefaultEncodingContext where it seems it 
now belongs.

Yeah, I poked around a few minutes. Seems we need to pass the header at the 
time when we do the encoding, rather than storing it in the EncodingContext. 
The changes for that are not entirely trivial.
An ugly way out might be a setter for the header in the EncodingContext and 
then set it when known, but that is too nasty and error prone. Maybe Dhruba has 
an idea...?

At this point I think I want to commit to and close this for 0.94 and file 
another jira for trunk. Any objections to that?

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.

Minor nit on v2: Don't need to create dataBlockEncodingStr if

 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.

Comment crossing again. Ah, I see, yes a problem in trunk too.
+1 on both patches.

Looks like the issue only exists in 0.94 branch.
There is no such code in trunk version of HFileDataBlockEncoderImpl.java:
{code}
*** 194,200 
DataBlockEncoding algo, boolean includesMemstoreTS) {
  ByteBuffer compressedBuffer = encodeBufferToHFileBlockBuffer(
  block.getBufferWithoutHeader(), algo, includesMemstoreTS,
- HFileBlock.DUMMY_HEADER);
{code}

Patch makes sense. Let's get Dhruba to have a look at it.
