Updates on this thread: I’ve discovered through trial & error that SQOOP 1.4.6 can export SEQUENCE files which have been created by SQOOP but it cannot read SEQUENCE files created by Hive.
Kind Regards Timothy Garza Database and BI Developer Collinson Technology Services Skype: timothy.garza.cts collinsongroup.com<http://www.collinsongroup.com/> [Collinson Group]<http://www.collinsongroup.com/> From: Timothy Garza [mailto:[email protected]] Sent: 03 September 2015 23:25 To: [email protected] Subject: SQOOP export of Sequence Files (Hive tables) Can we confirm or deny that Sqoop 1.4.6 can or can't export Sequence files to RDBMS via JDBC driver. I get an error from Sqoop regarding not being able to cast BytesWriteable to LongWriteable regardless of which data-type i'm reading from (in a Hive table) or writing to (MySQL or SQL Server table). There is no mention in the documentation of being able to export FROM (or not being able to export FROM) a Sequence File stored in HDFS. I can successfully SQOOP data from a TEXTFILE stored in HDFS but this sort of takes away the point of SQOOP and HDFS (in my opinion). Can anyone clarify this?
