[jira] [Updated] (SPARK-27434) memory leak in spark driver
[ https://issues.apache.org/jira/browse/SPARK-27434?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Ryne Yang updated SPARK-27434:
------------------------------
Description:
we got a OOM exception on the driver after driver has completed multiple jobs(we are reusing spark context).
so we took a heap dump and looked at the leak analysis, found out that under AsyncEventQueue there are 3.5GB of heap allocated. Possibly a leak.
can someone take a look at?
here is the heap analysis:
