New in HareDB-HBase-Client 1.98.01s (Jul 7, 2014)
- Upgraded runtime environment:
- Hadoop 2.3.X (using YARN)
- HBase 0.96+
- Since we have only test in Hadoop 2.3.X, but any version which is running YARN should be fine. (We recommend that using YARN)
- According to the huge update in HBase 0.94 to HBase 0.96, this version(1.98.x) of HareDB HBase Client is not fully functional in HBase 0.94. We¡¦d strongly recommend that you should update your HBase to version 0.96+.
