CompositeInputFormat doesn't consider all tuples when run in a local task tracker ---------------------------------------------------------------------------------
Key: MAPREDUCE-1223 URL: https://issues.apache.org/jira/browse/MAPREDUCE-1223 Project: Hadoop Map/Reduce Issue Type: Bug Affects Versions: 0.20.1 Environment: Yahoo distribution for Hadoop 0.20.1.3041192001 and Cloudera Distribution for Hadoop 0.20.1+133 Reporter: Ed Kohlwey The CrossJoin class does not emit all tuples representing the cross product of values for a given key. The issue only occurs when using the local task tracker, and not when running the job on a cluster. Example {noformat} table 1 k1 -> a table 2 k1 ->c k1 ->d {noformat} The expected output is {noformat} table 1 inner join table 2 k1->ac k1->ad {noformat} Instead one gets {noformat} table 1 inner join table 2 k1->ac {noformat} -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
