Matthias Boehm resolved SYSTEMML-749. ------------------------------------- Resolution: Fixed Fix Version/s: SystemML 0.11 > Failed nrow call after spark removeEmpty operation > -------------------------------------------------- > > Key: SYSTEMML-749 > URL: https://issues.apache.org/jira/browse/SYSTEMML-749 > Project: SystemML > Issue Type: Bug > Components: Runtime > Affects Versions: SystemML 0.10 > Reporter: Matthias Boehm > Assignee: Matthias Boehm > Fix For: SystemML 0.11 > > > In the special case of removeEmpty over a completely empty input matrix, the > spark removeEmpty instruction creates an invalid output of dimensions [0 x > ncol(in)] or [nrow(in) x 0] which is not supported in SystemML. Accordingly, > any subsequent operation would have undefined behavior; in case of meta data > operations like nrow or ncol, this actually leads to an explicit error with > the following message: "Invalid meta data returned by nrow: 0". -- This message was sent by Atlassian JIRA (v6.3.4#6332)
