Ufuk Celebi created FLINK-5276: ---------------------------------- Summary: ExecutionVertex archiving can throw NPE with many previous attempts Key: FLINK-5276 URL: https://issues.apache.org/jira/browse/FLINK-5276 Project: Flink Issue Type: Bug Components: JobManager Reporter: Ufuk Celebi Assignee: Stefan Richter Fix For: 1.2.0, 1.1.4
I saw a NPE while archiving a ExecutionVertex: {code} execution graph org.apache.flink.runtime.executiongraph.ExecutionGraph@c4e0722 for archiving. java.lang.NullPointerException: null at org.apache.flink.runtime.executiongraph.ExecutionVertex.prepareForArchiving(ExecutionVertex.java:583) at org.apache.flink.runtime.executiongraph.ExecutionJobVertex.prepareForArchiving(ExecutionJobVertex.java:439) at org.apache.flink.runtime.executiongraph.ExecutionGraph.prepareForArchiving(ExecutionGraph.java:1042) ... {code} I think this is due to the newly introduced {{EvictingBoundedList}} which returns a default element ({{null}})) for evicted elements when iterating over it. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
