[jira] [Updated] (HBASE-5795) hbase-3927 breaks 0.92<->0.94 compatibility

Zhihong Yu updated HBASE-5795:

Attachment: 5795-v2.txt
Patch v1 didn't make testHServerLoadVersioning pass.
Patch v2 does.
I found that the version of RegionLoad was actually serialized twice in 0.92:
first by VersionedWritable.write(), followed by RegionLoad.write().
In patch v2, I removed the redundant write. readFields92() consumes the second
copy of version.

Attachment: 5795-v1.txt
Since only deserialization needs special handling, the attached patch adds a
private method to read 0.92 RegionLoad.
Please comment.

Attachment: 5794.txt
Unit test that demonstrates the problem. It brings HSL from 0.92 into
src/test/java/o.a.h.h and then tries to have a 0.94/trunk HSL deserialize the
0.92 HSL. Currently it fails.
I'm thinking that we make this work by pressing on.. by including in HSL a
HSL092 to use deserializing 092 versions... or rather 092 versions of
HSL#RegionLoad. I think we need to press on because the second patch is a
legit fix -- converting requests from int to long to avoid our ever going
negative on read/write counts... I don't think we should revert this in 0.94.
