Sergey Sidorov created IGNITE-1384: -------------------------------------- Summary: Compute job ids duplication Key: IGNITE-1384 URL: https://issues.apache.org/jira/browse/IGNITE-1384 Project: Ignite Issue Type: Bug Reporter: Sergey Sidorov
Configure custom CollisionSpi with any implemenation which keeps waiting jobs list not empty. Execute considerable amount of tasks (e.g. 10000) from 2 or more nodes with jobs mapped to one node. Error occurs on mapped node: "Received computation request with duplicate job ID (could be network malfunction, source node may hang if task timeout was not set)" Reason: TaskGridWorker:processMappedJobs generates job ids as following: IgniteUuid jobId = IgniteUuid.fromUuid(node.id()); where node.id() is identifier of node the job is mapped to. So parallel generation of job ids on different nodes leads to ids duplication. Possible solution: use node.id() of local node in job id generation. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
