1. Upgrade HBase Applications
When you upgrade from HBase 0.98.12 to HBase 1.1, complete the following steps:
- Check existing HBase applications for API that is no longer supported in HBase 1.1 and then update the applications to use APIs supported by Hbase 1.1.
- Recompile applications with HBase 1.1. This steps is required even if the application did not require updates due to API changes.
