> PROBLEM: Running a sqoop import command with the option --create-hcatalog-table will not work due to the following reasons
> When create-hcatalog-table is used it creates the table as a Managed ACID table.
> HCatalog does not support transactional or bucketing table
> So customer who need to create a ORC based table cannot use sqoop to create a ORC based table which means their existing code where if in case they use sqoop to create these tables would fail.
> The current workaround is a two step process
> 1. Create the ORC table in hive with the keyword external and set transactional to false
> 2. Then use the sqoop command to load the data into the orc table.
> The request is to add in an extra argument in the sqoop command line to specify that the table is external (example: --hcatalog-external-table )so we can use the option --hcatalog-storage-stanza "stored as orc tblproperties (\"transactional\"=\"false\")".
