Subject [jira] [Commented] (HADOOP-9041) FileSystem initialization can go into infinite loop
Date Tue, 11 Dec 2012 01:51:22 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-9041?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13528598#comment-13528598

Andy Isaacson commented on HADOOP-9041:
---------------------------------------

bq. So this bug may be difficult to reproduce in junit environment. But in regular development,
it will be dangerous and hidden deep. Until here I think my patch can resolve this problem
and looking forward any comments. 

[~yanbo] could you post instructions for how to reproduce the infinite loop failure using
a simple java application?  I've tried to reproduce it using Eclipse+junit (using JDK 1.6.0_24
on Linux) and have not managed to cause the failure.  If you could upload or paste a standalone
testcase that fails, plus instructions for how to run it (on whatever platform) that will
help with manual testing.

> Referenced source code from example is: https://github.com/SpringSource/spring-hadoop/blob/master/src/main/java/org/springframework/data/hadoop/configuration/ConfigurationFactoryBean.java
> from isolating that cause it looks like if you register: org.apache.hadoop.fs.FsUrlStreamHandlerFactory
before calling FileSystem.loadFileSystems() then it goes into infinite loop.
