Kuan-Po Tseng updated HBASE-21012:
----------------------------------
Release Note: HFiles generated by 2.0.0, 2.0.1, 2.1.0 are not forward
compatible to 1.4.6-, 1.3.2.1-, 1.2.6.1-, and other inactive releases. Why
HFile lose compatability is hbase in new versions (2.0.0, 2.0.1, 2.1.0) use
protobuf to serialize/deserialize TimeRangeTracker (TRT) while old versions use
DataInput/DataOutput. To solve this, We have to put HBASE-21012 to 2.x and put
HBASE-21013 in 1.x. For more information, please check HBASE-21008.
> Revert the change of serializing TimeRangeTracker
