Review request for Sqoop.


I added a check when generating the create table string to see if the LzopCodec is in use.
If it is, it outputs

STORED AS INPUTFORMAT "com.hadoop.mapred.DeprecatedLzoTextInputFormat"
OUTPUTFORMAT "org.apache.hadoop.hive.ql.io.HiveIgnoreKeyTextOutputFormat"

at the end of the create table command, otherwise it outputs the standard


I also added a call to the DistributedLzoIndexer before the data is imported into Hive.

This addresses bug SQOOP-318.

It includes a test for the create table syntax. I manually tested calling the indexer. I'm
not sure how to automate that without making LZO required to build.

> When importing LZO compressed files into Hive, it would be useful to create the hive
table with the com.hadoop.mapred.DeprecatedLzoTextInputFormat. It would also be nice to automatically
run the DistributedIndexer so that the LZO files can be split.
