Subject [jira] [Commented] (HADOOP-8146) FsShell commands cannot be interrupted
Date Wed, 07 Mar 2012 16:40:58 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-8146?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13224490#comment-13224490

Daryn Sharp commented on HADOOP-8146:

# I think it's overall a good idea, but dfsadmin is still subclassing FsShell/Command.  It's
not using the rest of the logic, but I'd rather not change nor risk destabilizing that command
at this time.  Would you be willing to file a new jira?
# I wish I could, but the commands do not have public visibility to prevent direct instantiation.
 All the loops for processing paths including a try loop that catches IOException, so interrupts
are always converted to exceptions.  The 2nd interrupt test does already exercise recursion
into a directory.

Let me know if you want me to make further changes.

> Control-c is apparently generating {{InterruptedIOExceptions}}.  The path processing
loop traps {{IOException}}, displays the error, and moves to the next path.  This means that
recursive operations cannot be aborted.
