Examples of org.apache.hadoop.hbase.filter.TimestampsFilter

org.apache.hadoop.hbase.filter.TimestampsFilter
Filter that returns only cells whose timestamp (version) is in the specified list of timestamps (versions).
Note: Use of this filter overrides any time range/time stamp options specified using {@link org.apache.hadoop.hbase.client.Get#setTimeRange(long,long)}, {@link org.apache.hadoop.hbase.client.Scan#setTimeRange(long,long)}, {@link org.apache.hadoop.hbase.client.Get#setTimeStamp(long)}, or {@link org.apache.hadoop.hbase.client.Scan#setTimeStamp(long)}.
