[jira] [Created] (FLINK-5276) ExecutionVertex archiving can throw
NPE with many previous attempts
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.
