    we are currently using the Hive JDBC connector (CDH3) and wanted to know how much work should we expect to port our existing code to work with HDP?

    thanks,

    Allan

    Hi Alan,

    HDP 1.0.x ships with Hive 0.8.y (current one is 0.8.1 to be precise)
    In order to port to HDP, along with Hive installation you will need to upgrade Hive metastore from hive 0.7 to 0.8 (there are scripts available to do this for MySql metastore)

    Apart from this, your application code wouldn’t need any changes and it should just work with HDP (unless you want to take advantages of new features)

    Regards,
    Sheetal
