Hudson commented on SQOOP-474: ------------------------------ Integrated in Sqoop-ant-jdk-1.6 #107 (See [https://builds.apache.org/job/Sqoop-ant-jdk-1.6/107/]) SQOOP-474 Split-by specification incorrectly triggers bounding value query (Revision 1310129) Result = SUCCESS blee : Files : * /sqoop/trunk/src/java/org/apache/sqoop/mapreduce/DataDrivenImportJob.java > Split-by specification incorrectly triggers bounding value query > ---------------------------------------------------------------- > > Key: SQOOP-474 > URL: https://issues.apache.org/jira/browse/SQOOP-474 > Project: Sqoop > Issue Type: Bug > Components: build, connectors/generic > Affects Versions: 1.4.1-incubating > Reporter: Kathleen Ting > Assignee: Kathleen Ting > Fix For: 1.4.2-incubating > > Attachments: SQOOP-474-1.patch, SQOOP-474.patch > > > To reproduce this, run an import using a query with number of mappers set to > 1 and a split-by specification. For example: > {code} > $ sqoop import --connect jdbc:mysql://localhost/hadoopguide --query 'SELECT > A.*, B.* FROM A JOIN B ON (A.AID = B.BID) WHERE $CONDITIONS' --split-by AID > --target-dir /user/kateting/test1 --m=1 > {code} > This import will output the following: > {code} > 12/04/02 13:29:59 INFO db.DataDrivenDBInputFormat: BoundingValsQuery: SELECT > MIN(AID), MAX(AID) FROM (SELECT A.*, B.* FROM A JOIN B ON (A.AID = B.BID) > WHERE (1 = 1) ) AS t1 > {code} > An embedded query fails in DB2 when using the 'with ur' syntax. This also > fails for Informix if the version of Informix doesn't support embedded > queries. The issue is the 'with ur' syntax, without which, the boundary query > is harmless. The boundary query is being triggered because of the split-by > specification. However specifying split-by is redundant given that the number > of mappers is 1. -- This message is automatically generated by JIRA.
