• Type: Bug
• Status: Open
• Priority: Not a Priority
• Resolution: Unresolved
• Affects Version/s: 1.1.0
• Component/s: Runtime / Network
• Labels: auto-deprioritized-critical auto-deprioritized-major auto-deprioritized-minor
• Assignee: Unassigned
• Reporter: Greg Hogan
• Created: 06/Jul/16 19:44

Description

Discovered the following deadlock while running Gelly's undirected.TriangleListing. There are two TaskManagers. As shown in the screenshot, GroupReduce is sending data to Join. The GroupReduce look to all be waiting while requesting a buffer. From where would these buffers be released?
