Anoop Sam John updated HBASE-10321:
-----------------------------------
Description:
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 won't 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. ..
This makes tags not supported via CellCodec..Tag support can be added to
CellCodec once we have Connection negotiation in place (?)
