----------------------------------------
{quote}What is preferred here?

Here's is my two cents.
# Since we have released 2.0 and 2.1, backporting only the "read" part to 1.x
is necessary.
# if all 1.x deployment should work with hfiles generated by 2.x, we can file
another Jira to change the serialization from protobuf to previous way. (of
course, the hfiled impacted by HBASE-18754 still can't work with 1.x...:()
> HBase 1.x can not read HBase2 hfiles due to TimeRangeTracker

> I tested the latest HBase 1.4.6 and 2.1.0. 1.4.6 tried to read and open
