Subject [jira] [Commented] (LUCENE-4245) IndexWriter#close(true) should either not be interruptible or should abort background merge threads before returning
Date Mon, 23 Jul 2012 12:09:34 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-4245?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13420594#comment-13420594

Uwe Schindler commented on LUCENE-4245:
---------------------------------------

I think my patch does exactly that. If you call close() and one interrupts it, you still get
a closed reader (and the Exception).

Another fix in Solr code would be do make the part that calls IndexWriter.close() be a while
loop as long as a ThreadInterruptedException is catched.

> Currently, there is no safe way to close a directory after closing the writer without
causing an exception in a merge thread if the #close call is interrupted.
