Summary: tryAllocate:
Key: YUNIKORN-1246
URL: https://issues.apache.org/jira/browse/YUNIKORN-1246
Project: Apache YuniKorn
Issue Type: Bug
Components: core - common
Affects Versions: 1.1.0
Reporter: Wilfred Spiegelenburg
Assignee: Wilfred Spiegelenburg
When an ask has a required node set we only try to allocate the one specific
node. In tryAllocate we have two issues:
* The node specified as the required node might not exist. In that case the
scheduler crashes with a nil pointer
* If the release of a preempted allocation is processed during the scheduling
cycle we might try to allocate the ask on the node via the normal tryAllocate
and not use the tryReservedAllocate flow. If that happens we leave the node
reserved forever and that makes the node unusable.
