Jian Zhang commented on HDFS-17503: ----------------------------------- Can you describe in detail how oom came about? > Unreleased volume references because of OOM > ------------------------------------------- > > Key: HDFS-17503 > URL: https://issues.apache.org/jira/browse/HDFS-17503 > Project: Hadoop HDFS > Issue Type: Bug > Reporter: Zilong Zhu > Assignee: Zilong Zhu > Priority: Major > > When BlockSender throws an error because of OOM,the volume reference obtained > by the thread is not released,which causes the thread trying to remove the > volume to wait and fall into an infinite loop. > I found HDFS-15963 catched exception and release volume reference. But it did > not handle the case of throwing errors. I think "catch (Throwable t)" should > be used instead of "catch (IOException ioe)". -- This message was sent by Atlassian Jira (v8.20.10#820010) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
