[jira] [Updated] (CASSANDRA-15949) NPE thrown while updating
speculative execution time if table is removed during task execution
[ https://issues.apache.org/jira/browse/CASSANDRA-15949?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Jon Meredith updated CASSANDRA-15949:
-------------------------------------
Bug Category: Parent values: Degradation(12984)
Complexity: Normal
Discovered By: User Report
Severity: Normal
Status: Open (was: Triage Needed)
Marked this as a degradation as from https://docs.oracle.com/javase/8/docs/api/java/util/concurrent/ScheduledThreadPoolExecutor.html#scheduleAtFixedRate-java.lang.Runnable-long-long-java.util.concurrent.TimeUnit-
"If any execution of the task encounters an exception, subsequent executions are suppressed"
So if this hits while a table is being dropped, recomputation of speculative retry thresholds will halt node-wide.
