org.apache.hadoop.hbase.thrift2.generated.TGet
Used to perform Get operations on a single row. The scope can be further narrowed down by specifying a list of columns or column families. To get everything for a row, instantiate a Get object with just the row to get. To further define the scope of what to get you can add a timestamp or time range with an optional maximum number of versions to return. If you specify a time range and a timestamp the range is ignored. Timestamps on TColumns are ignored.
