Sqoop import failed after initial import

  • #31577

    I’ve imported a table from SQL Server 2008 R2 to Hive using SQOOP. It worked but when I dropped the table in Hive and reimport I’m getting following error

    Hi SUNDARARAJ,

    Looks like the error is :
    Output directory MPTest already exists

    Can you please try specifying new directory?

    Hope this helps,

    Thanks,
    Seth

    Thanks. I deleted the directory and it is working fine. I’m trying to add a xml mapper in Groovy to Transform XML in hive Select. I’m getting an error

    Can you please let me know how to use Groovy script in Hive?
