Hi, 
we tried to download and compile your hive-exec-0.10-mapr.jar in order to fix the join bug we noticed on [Jira - HIVE-4730][1] 

i downloaded the 0.10 version from [your git repository][2], 
i checked the code is right (compared it to patch [patch 4730.v2][3]) and compile it (ant clean, then ant maven-build). 
then i copied the /usr/src/hive-10-mapr/hive-branch-0.10-mapr/build/maven/jars/hive-exec-0.10-mapr.jar to /opt/mapr/hive/hive-0.10/lib/.

when i run the join it still returning 1 row instead of 2^31 rows.. 
as you can see in the reducer log: 

    2013-12-24 23:22:17,296 INFO org.apache.hadoop.hive.ql.exec.FileSinkOperator: TABLE_ID_1_ROWCOUNT:1 

any idea why your version on hive-10 , which i saw is after the related patch, still have the bug?

Thanks, 
Gabi
