HCatalog presents a relational view of data. Data is stored in tables and these tables can be placed into databases. Tables can also be partitioned on one or more keys. For a given value of a key (or set of keys) there will be one partition that contains all rows with that value (or set of values).
hcat.py -g mygrpoup ... # Indicates to HCatalog that table that needs to be created must have group as "mygroup" hcat.py -p rwxr-xr-x ... # Indicates to HCatalog to set permissions as "rwxr-xr-x" hcat.py -f myscript.hcatalog ... # Indicates to HCatalog that myscript.hcatalog is a file which contains DDL commands it needs to execute hcat.py -e "create table mytrable (a int) ... # Indicates to HCatalog to treat the following string as DDL command and execute it
