Subject Re: Unable to import tables from sqoop
Date Mon, 06 Aug 2012 19:06:41 GMT
Hi Prabhjot,

If you have not resolved this issue already, there is another way to do
this using 1.4.1 and that is by using --query tag and "select * from
mytable" like below. Import table does not work, but select * works in
1.4.1.

sqoop import --connect
'jdbc:sqlserver://mysqlserver;username=myuserid;password=mypassword;database=mydatabase'
--query 'select  * from mytable with(nolock) where $CONDITIONS'
--num-mappers 10 --split-by 'rowid' --target-dir /user/hadoop/mydir
 --hive-import --hive-drop-import-delims --hive-overwrite --hive-table
myhivetable --hive-partition-key mykey --hive-partition-value mypartition

Hope this helps!
Chalcy
