Doug Cutting commented on HADOOP-327: ------------------------------------- But at issue here is not a particular main(), but an interface for main()-like methods. So we cannot know which specific exceptions might be thrown. > ToolBase calls System.exit > -------------------------- > > Key: HADOOP-327 > URL: http://issues.apache.org/jira/browse/HADOOP-327 > Project: Hadoop > Type: Bug > Components: util > Versions: 0.4.0 > Reporter: Owen O'Malley > Assignee: Hairong Kuang > Fix For: 0.5.0 > Attachments: exit.patch > > The new ToolBase class calls System.exit when the main routine finishes. That > will break if the application uses threads that need to finish before the jvm > exits. The normal semantics is that the program doesn't finish execution > until all of the non-daemon threads exit (including the main one) and > System.exit should never be called except for critical errors. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://issues.apache.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
