> Sqoop (HADOOP-5815) imports tables into HDFS; it is a straightforward enhancement to then generate a Hive DDL statement to recreate the table definition in the Hive metastore and move the imported table into the Hive warehouse directory from its upload target.
> This feature enhancement makes this process automatic. An import is performed with sqoop in the usual way; providing the argument "--hive-import" will cause it to then issue a CREATE TABLE .. LOAD DATA INTO statement to a Hive shell. It generates a script file and then attempts to run "$HIVE_HOME/bin/hive" on it, or failing that, any "hive" on the $PATH; $HIVE_HOME can be overridden with --hive-home. As a result, no direct linking against Hive is necessary.
> The unit tests provided with this enhancement use a mock implementation of 'bin/hive' that compares the script it's fed with one from a directory full of "expected" scripts. The exact script file referenced is controlled via an environment variable. It doesn't actually load into a proper Hive metastore, but manual testing has shown that this process works in practice, so the mock implementation is a reasonable unit testing tool.
