Subject [jira] Commented: (HADOOP-6762) exception while doing RPC I/O closes channel
Date Thu, 10 Jun 2010 01:28:14 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-6762?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12877286#action_12877286
] 

sam rash commented on HADOOP-6762:
----------------------------------

this is downright odd--if I click and view

https://issues.apache.org/jira/secure/attachment/12446356/hadoop-6762-7.txt
https://issues.apache.org/jira/secure/attachment/12446530/hadoop-6762-8.txt

they differ (the latter has a Thread.sleep() in the unit test)

but grabbing with wget 

wget https://issues.apache.org/jira/secure/attachment/12446530/hadoop-6762-7.txt --no-check-certificate
wget https://issues.apache.org/jira/secure/attachment/12446530/hadoop-6762-8.txt --no-check-certificate

they both have the Thread.sleep()

is something up with JIRA?  or what did I do?

> If a single process creates two unique fileSystems to the same NN using FileSystem.newInstance(),
and one of them issues a close(), the leasechecker thread is interrupted.  This interrupt
races with the rpc namenode.renew() and can cause a ClosedByInterruptException.  This closes
the underlying channel and the other filesystem, sharing the connection will get errors.
