1. Upgrade HBase Applications

When you upgrade from HBase 0.98.12 to HBase 1.1, complete the following steps:

  1. 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.
  2. Recompile applications with HBase 1.1. This steps is required even if the application did not require updates due to API changes.
