Examples of org.apache.hadoop.hbase.security.User

org.apache.hadoop.hbase.security.User
Wrapper to abstract out usage of user and group information in HBase.
This class provides a common interface for interacting with user and group information across changing APIs in different versions of Hadoop. It only provides access to the common set of functionality in {@link org.apache.hadoop.security.UserGroupInformation} currently needed byHBase, but can be extended as needs change.
