The two main issues are: > # lease monitor thread does not sleep if an exception occurs before looping > again > # the loop peeks at the first element of a sorted tree set so when an > exception occurs, the "bad" lease remains as the first element preventing > recovery of other leases. > This jira is not intended to fix the underlying issues causing the exception > during recovery but merely to mitigate the cited issues. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
