[jira] [Updated] (SPARK-33220) `scheduleAtFixedRate` change to
`schedulerWithFixedDelay` to avoid repeated unecessary scheduling for a
short time
[ https://issues.apache.org/jira/browse/SPARK-33220?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
angerszhu updated SPARK-33220:
------------------------------
Description:
For some schedule behavior, we will `scheduleAtFixedRate` to schedule task or heartbeat RPC etc...
If thread blocked by a big fullGc or other reason cause delay, will schedule task repeatedly. For some behavior it's not necessary. We can use `scheduleWithFixedDelay` to avoid it.
