--------------------------------------
Summary: CellCodec has broken the 96 client to 98 server
compatibility
Key: HBASE-10321
URL: https://issues.apache.org/jira/browse/HBASE-10321
Project: HBase
Issue Type: Bug
Affects Versions: 0.98.0
Reporter: Anoop Sam John
Assignee: Anoop Sam John
Priority: Critical
Fix For: 0.98.0, 0.99.0
The write/read tags added in CellCodec has broken the 96 client to 98 server
compatibility (and 98 client to 96 server)
When 96 client CellCodec writes cell, it wont write tags part at all. But the
server expects a tag part, at least a 0 tag length. This tag length read will
make a read of some bytes from next cell!
I suggest we can remove the tag part from CellCodec. This codec is not used by
default and I don't think some one will change to CellCodec from the default
KVCodec now. .. Still I feel we can solve it.
This makes tags not supported via CellCodec..Tag support can be added to
CellCodec once we have Connection negotiation in place (?)
