      Description

      Command I am running:
      sqoop import --connect jdbc:mysql://<mysqlhost>/mysqltestdb --username xxx --password xxxx --query 'select testtable.id, testtable2.fname from testtable join testtable2 on (testtable.id = testtable2.id ) where testtable.id < 3 AND $CONDITIONS' --split-by testtable.id --target-dir joinresults

      Sqoop fails with this error message

      2/03/02 12:12:08 INFO db.DataDrivenDBInputFormat: BoundingValsQuery: SELECT MIN(testtable.id), MAX(testtable.id) FROM (select testtable.id as id, testtable2.fname as fname from testtable join testtable2 on (testtable.id = testtable2.id ) where testtable.id < 3 AND  (1 = 1) ) AS t1
      12/03/02 12:12:08 INFO mapreduce.JobSubmitter: Cleaning up the staging area /user/prashant/.staging/job_1330641624236_0016

      The job runs successfully if I modify the query:

      sqoop import --connect jdbc:mysql://<mysqlhost>/mysqltestdb --username xxxx --password xxxx --query 'select t1.id as id, t2.fname as fname from testtable as t1 join testtable2 as t2 on (t1.id = t2.id ) where t1.id < 3 AND $CONDITIONS' --split-by t1.id --target-dir joinresults

      It would be nice to have it documented at least.
