sqoop import from vertica failed

问题

I am trying to import dataset from Vertica to HDFS using sqoop2.

I a running following query on sqoop machines to import data into hdfs from Vertica v6.0.1-7

sqoop import -m 1 --driver com.vertica.jdbc.Driver --connect "jdbc:vertica://10.10.10.10:5433/MYDB" --password dbpassword --username dbusername --target-dir "/user/my/hdfs/dir" --verbose --query 'SELECT * FROM ORDER_V2 LIMIT 10;'

but i am getting some error here,

16/02/03 10:33:17 ERROR tool.ImportTool: Encountered IOException running import job: java.io.IOException: Query [SELECT * FROM ORDER_V2 LIMIT 10;] must contain '$CONDITIONS' in WHERE clause.

Anyone knows how to do this, considering different username on both machines.

回答1:

after adding vertica_5.1.4_jdk_5.jar to /var/lib/sqoop

and Addition of WHERE $CONDITIONS solved the issue

sqoop import -m 1 --driver com.vertica.jdbc.Driver --connect "jdbc:vertica://10.10.10.10:5433/MYDB" --password dbpassword --username dbusername --target-dir "/user/my/hdfs/dir" --verbose --query 'SELECT * FROM ORDER_V2 WHERE $CONDITIONS;'
