------------------------------------
Summary: Fix the map-reduce join for a complex reducer on
map-reduce mode
Key: MRQL-44
URL: https://issues.apache.org/jira/browse/MRQL-44
Project: MRQL
Issue Type: Bug
Components: Run-Time/MapReduce
Affects Versions: 0.9.4
Reporter: Leonidas Fegaras
Assignee: Leonidas Fegaras
Attachments: MRQL-44.patch
The hadoop map-reduce join must cache the result of the reduce function in
memory. Normally, the result is a lazy bag (stream-based), but when data is
complex, this bag must be cached in memory as a vector. It fixes a bug reported
by Eldon Carman. The attached patch fixes the bug.
