Subject [jira] Commented: (HDFS-1504) FSImageSaver should catch all exceptions, not just IOE
Date Wed, 17 Nov 2010 20:33:16 GMT

    [ https://issues.apache.org/jira/browse/HDFS-1504?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12933143#action_12933143
] 

Todd Lipcon commented on HDFS-1504:
-----------------------------------

Exception won't catch failed asserts (AssertionError inherits from Error <- Throwable,
not Exception)

> FSImageSaver currently just catches IOE. This means that if some other error like OOME
or failed assert happens in saving one of the images, the coordinating thread won't know there
was a problem.
