Subject [jira] [Commented] (MAPREDUCE-4764) repair test org.apache.hadoop.mapreduce.security.TestBinaryTokenFile
Date Fri, 02 Nov 2012 17:45:12 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-4764?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13489579#comment-13489579

Robert Joseph Evans commented on MAPREDUCE-4764:
------------------------------------------------

Daryn,

For the hdfs mini cluster it is all running in the same process, but for MR it is not.  They
actually do launch separate processes, even though the NM and RM are running the same process
the AM and tasks are not.

> the test is @Ignore-ed, and fails being enabled.
> Suggested to repair it to fill the coverage gap.
> Problems fixed in the test: 
> (1) MRConfig.FRAMEWORK_NAME and YarnConfiguration.RM_PRINCIPAL properties must be correctly
set in the configuration to correctly enable the security in the way this test implies. 
> (2) The property MRJobConfig.MAPREDUCE_JOB_CREDENTIALS_BINARY now is not passed into
the Job configuration -- it is intentionally deleted from there. So, we pass the binary file
name in another dedicated property. 
> (3) The test was using deprecated cluster classes. All them are updated to the modern
analogs.
> (4) The delegation token found in the job context is now correctly compared to the one
deserialized from the binary file.
