Examples of IndexSpecification

org.apache.hadoop.hbase.client.tableindexed.IndexSpecification
Holds the specification for a single secondary index.
org.apache.hadoop.hbase.index.IndexSpecification
An IndexSpecification should have a unique name and can be created on 1 or more columns (Here column refers to columnfamily + qualifier) For each of such column a ColumnQualifier is provided which takes the column details. This includes the column family name and qualifier name. The additional columns are those columns in the main table whose value also will be captured in the secondary index table. Index Specfication name should not start with '.' and '-'. Can contain alphanumerics and '-','.','_'.
