Importing Data Into HBase
^^^^^^^^^^^^^^^^^^^^^^^^^

Sqoop supports additional import targets beyond HDFS and Hive. Sqoop
can also import records into a table in HBase.

By specifying +\--hbase-table+, you instruct Sqoop to import
to a table in HBase rather than a directory in HDFS. Sqoop will
import data to the table specified as the argument to +\--hbase-table+.
Each row of the input table will be transformed into an HBase
+Put+ operation to a row of the output table. The key for each row is
taken from a column of the input. By default Sqoop will use the split-by
column as the row key column. If that is not specified, it will try to
identify the primary key column, if any, of the source table. You can
manually specify the row key column with +\--hbase-row-key+. Each output
column will be placed in the same column family, which must be specified
with +\--column-family+.

NOTE: This function is incompatible with direct import (parameter 
+\--direct+).

If the target table and column family do not exist, the Sqoop job will
exit with an error. You should create the target table and column family
before running an import. If you specify +\--hbase-create-table+, Sqoop
will create the target table and column family if they do not exist,
using the default parameters from your HBase configuration.

Sqoop currently serializes all values to HBase by converting each field
to its string representation (as if you were importing to HDFS in text
mode), and then inserts the UTF-8 bytes of this string in the target
cell.
