New in This Release

This is the initial MapR release of HBase 1.1. In addition to HBase 1.1 features, this release includes the following feature that is specific to MapR:
  • Default Database Setting.

    When you run configure.sh, a default database for HBase clients is automatically set based on the packages available on the cluster. When mapr-hbase-regionserver or mapr-hbase-master packages are installed on the cluster, HBase is the default database for all HBase client connections. You can use the configure.sh -defaultdb option to change the default database setting for the cluster or you specify a value to override the default in the HBase job configuration or the hbase-site.xml. For more information, see MapR's HBase and confgure.sh documentation.

  • Default Ports

    The following ports for HBase 1.1 are changed:

    Table 1. HBase Default Ports
