    Hi,

    in my HCatalog-0.4.1\bin directory are only three files:
    “hcat” – a bash script
    “hcat.py” – a python skript
    “hcatcfg.py” – another python script

    How can I run HCatalog with Windows’ cmd directly?

    Best regards

    Hi,

    Some usage information is below:

    usage: hcat { -e “” | -f “” } [ -g “” ] [ -p “” ]
    [ -D”=” ]
    -D use hadoop value for given property
    -e hcat command given from command line
    -f hcat commands in file
    -g group for the db/table specified in CREATE statement
    -h,–help Print help information
    -p permissions for the db/table specified in CREATE statement

    Hope this helps,

    Thanks,
    Seth

    Hi,

    You can run “hcat.py” under hadoop command line window, you will see the detail parameter and describe.
    e.g: hcat.py -e “create table student(id int, name string, score int)”
    Hope this helps.
