Glenn Weidner updated SYSTEMML-1616: ------------------------------------ Fix Version/s: (was: SystemML 1.0) SystemML 0.15 > Multi-threaded JMLC failures due to side effects of constant folding > -------------------------------------------------------------------- > > Key: SYSTEMML-1616 > URL: https://issues.apache.org/jira/browse/SYSTEMML-1616 > Project: SystemML > Issue Type: Bug > Reporter: Matthias Boehm > Assignee: Matthias Boehm > Fix For: SystemML 0.15 > > > In scenarios with multiple concurrently running JMLC connections and prepared > scripts per JVM process (e.g., in spark executors, or multi-threaded > containers), there are potential side effects between scripts which > ultimately can lead to compilation and runtime errors. > The root cause are static reuse objects (for program block and execution > context) in the constant folding rewrite. Accordingly, folded constants might > leak from one script compilation into another script compilation which can > cause all sorts of incomprehensible errors. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
