while importing tables from mysql to hive using sqoop you can import using hive-import argument as well as hcatalog-table argument. I am bit confuse about how to select between hive and hcatalog option as both imports to hive database tables.
Is there any specific condition to use --hive-import and --hcatalog-table arguments to import using sqoop ?
Actually the hive commands should result mainly in hcatalog commands for most table operation. I only found this hint:
HCatalog supports all Hive Data Definition Language except those operations that require running a MapReduce job. For commands that are supported, any variances are noted below.
I have not checked if there is any difference in performance, but I doubt it would be significant.
