Using Snappy Compression in Sqoop 1 and Sqoop 2 Imports

For Sqoop 1:
On the command line, use the following option to enable Snappy compression:
```
--compression-codec org.apache.hadoop.io.compress.SnappyCodec
```
It is a good idea to use the --as-sequencefile option with this compression option.
For Sqoop 2:
When you create a job (sqoop:000> create job), choose 7 (SNAPPY) as the compression format.
