Subject [jira] Commented: (HADOOP-4467) SerializationFactory should use current context ClassLoader
Date Wed, 22 Oct 2008 07:04:44 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-4467?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12641729#action_12641729
] 

Chris K Wensel commented on HADOOP-4467:
----------------------------------------

All but org.apache.hadoop.fs.TestLocalDirAllocator tests pass. 

I think this is unrelated:
shell-init: error retrieving current directory: getcwd: cannot access parent directories:
No such file or directory

> SerializationFactory#add calls Class.forName without a ClassLoader instance. This prevents
user-space Serialization classes from being loaded.
> The resulting ClassNotFoundException is eaten after being logged, and a NPE is thrown
further down the line when a Serializer is requested.
