Summary: ThrottledAsyncChecker is not thread-safe. Key: HDFS-15249 URL: https://issues.apache.org/jira/browse/HDFS-15249 Project: Hadoop HDFS Issue Type: Bug Reporter: Toshihiro Suzuki Assignee: Toshihiro Suzuki ThrottledAsyncChecker should be thread-safe because it can be used by multiple threads when we have multiple namespaces. *checksInProgress* and *completedChecks* are respectively HashMap and WeakHashMap which are not tread-safe. So we need to put them in synchronized block whenever we access them. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-dev-h...@hadoop.apache.org
