-----------------------------
Summary: Bug that IndexedRowMatrix.computeSVD() yields the U with
wrong numCols
Key: SPARK-8563
URL: https://issues.apache.org/jira/browse/SPARK-8563
Project: Spark
Issue Type: Bug
Components: MLlib
Affects Versions: 1.3.1
Reporter: 19 Lee
IndexedRowMatrix.computeSVD() yields a wrong U which *U.numCols() = self.nCols*.
It should have been *U.numCols() = k = svd.U.numCols()*
{code}
(m x n) = (m x n) * (k x k) * (k x n)
-->
(m x n) = (m x k) * (k x k) * (k x n)
{code}
Proposed fix: https://github.com/apache/spark/pull/6949
