---------------------------------------
Summary: Mismatch between expected and actual nonzeros when
writing sparse to ultrasparse matrixblock
Key: SYSTEMML-1137
URL: https://issues.apache.org/jira/browse/SYSTEMML-1137
Project: SystemML
Issue Type: Bug
Reporter: Felix Schüler
When writing a sparse to ultrasparse matrixblock in
MatrixBlock.writeSparseToUltraSparse() an exception is thrown that indicates a
mismatch in counted and expected nonzeros.
One quick solution is to add a recomputeNonzeros to the ReorgCPInstruction to
keep the nonzeros up to date. I am not sure though if we want to do this after
every reorg or if the mismatch comes from another place.
