Hi, a very simple question: Is there a difference between a table in Hive and a table in HCat? In other words: Can I create a table in Hive that is invisible in HCat, or vice versa? (Assuming that Hive and HCat point to the same metastore)
>From my understanding, HCat is just a wrapper around the Hive metastore, so there should be no major difference. This is in line with my experience: If I create a table via the Hive CLI, it will be shown in HCat too when running hcat -e "show tables;". And vice versa. I ask because some online documentation makes me feel that I have to run my DDL in HCat to make it visible there. At least I didn't find documents that say that I can use either Hive CLI or HCat. Thanks, André Hacker
