Summary: dals failing in Flink-bindings
Key: MAHOUT-1818
URL: https://issues.apache.org/jira/browse/MAHOUT-1818
Project: Mahout
Issue Type: Bug
Components: Flink
Affects Versions: 0.11.2
Reporter: Andrew Palumbo
Assignee: Andrew Palumbo
Priority: Blocker
Fix For: 0.12.0
{{dals}} test fails in Flink bindings with an OOM. Numerically the test
passes, when the matrix being decomposed in the test lowered to the size 50 x
50. But the default size of the matrix in the
{{DistributedDecompositionsSuiteBase}} is 500 x 500.
