Subject [jira] [Commented] (HDFS-3012) Exception while renewing delegation token
Date Fri, 24 Feb 2012 23:21:54 GMT

    [ https://issues.apache.org/jira/browse/HDFS-3012?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13216088#comment-13216088

Robert Joseph Evans commented on HDFS-3012:
-------------------------------------------

@Mahadev,

The Renewer is already static.  The issue is that the Renewer code has no direct interaction
with HdfsConfiguration.  Just an include is not enough to ensure that java will load the class
and run the static block.  In the past, and in most other locations the HDFS Client would
create an instance of HDFSConfiguration to access any configuration values.  This would force
it to load, but because the RM does not interact with HDFS at all, except to renew and cancel
tokens that interaction with HdfsConfiguration must be on the execution path of the Renewer.
