Thanks Jarcec for the update, So Sqoop is not suitable for shifting data from DB to HDFS , if some columns have integer[] or bigint[] datatypes.
Is there any way i can sh*ift date having bigint[] datatypes from* postgresql DB to HDFS using Sqoop or I need to test another tool like Talend etc. Thanks On Thu, Aug 23, 2012 at 11:45 PM, Jarek Jarcec Cecho <[email protected]>wrote: > Hi Adarsh, > as far as I know then Sqoop should not have any issues with bigint data > type. > > Based on provided log fragment, It seems that you're having issues with > SQL type 2003 that should be ARRAY (see 1).
