Trevor Grant created MAHOUT-1971: ------------------------------------ Summary: Aggregate Transpose Bug Key: MAHOUT-1971 URL: https://issues.apache.org/jira/browse/MAHOUT-1971 Project: Mahout Issue Type: Bug Reporter: Trevor Grant Assignee: Trevor Grant Fix For: 0.13.1
In the At operation of Flink and spark there is a line that looks like: case (row, blockRow) => colV(row) = blockA(blockRow, blockCol) that ought to be case (row, blockRow) => colV(row) += blockA(blockRow, blockCol) Since it isnt'- the 'aggregate transpose' does not operate as expected. This needs to be updated in the Spark and Flink bindings (same one char fix). Test coverage should be updated to catch this. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
