0.94 has been EOL for a very long time... The guys from Xiaomi gave a presentation on HBaseCon West 2017 where they talked about something about migrating from 0.94 to 0.98
https://www.slideshare.net/HBaseCon/hbase-at-xiaomi Starting from page 6 I think the only way is to copy snapshots, as the rpc protocol had been changed from writable to protobuf between 0.94 and 0,98. But I'm not sure if copying snapshots to 2.2.x could work, as the HFile version may be changed. You could have a try. If it does not work, then you need to manually backport some patches I guess. The final solution if you do not want to patch HBase, is to read all the data and then store it in another format, like json or something, and then write it to the new hbase cluster. In this way the migration will be slow but it could work. Thanks.
