Harsh J resolved HDFS-112.
--------------------------
Resolution: Not A Problem
This JIRA has grown stale over years and needs to be closed. The tests
framework has changed considerably since '06.
With the current mini clusters, giving a hosts array is possible for different
hostnamed daemons, and by all the tests it carries, it does appear to work
alright if you wanna use it for such purposes.
> ClusterTestDFS fails
> --------------------
>
> Key: HDFS-112
> URL: https://issues.apache.org/jira/browse/HDFS-112
> Project: Hadoop HDFS
> Issue Type: Bug
> Environment: local workstation (windows)
> Reporter: alan wootton
> Assignee: Sameer Paranjpye
> Attachments: ClusterTestFixes.patch, fix_clustertestdfs.patch
>
>
> The dfs unit tests, from the ant target 'cluster' have been failing.
> (ClusterTestDFSNamespaceLogging, ClusterTestDFS). I don't know if anyone but
> me cares about these tests, but I do. I would like to write better tests for
> dns. I think we all need that.
> They have been partially broken since "test.dfs.same.host.targets.allowed"
> went away and replication ceased for these tests.
> They got really broken when NameNode stopped automatically formatting itself .
> Since they seem to be ignored, I took the liberty of changing how they work.
> The main thing is, you must put this into your hosts file:
> 127.0.0.1 localhost0
> 127.0.0.1 localhost1
> 127.0.0.1 localhost2
> 127.0.0.1 localhost3
> 127.0.0.1 localhost4
> 127.0.0.1 localhost5
> 127.0.0.1 localhost6
> 127.0.0.1 localhost7
> 127.0.0.1 localhost8
> 127.0.0.1 localhost9
> 127.0.0.1 localhost10
> 127.0.0.1 localhost11
> 127.0.0.1 localhost12
> 127.0.0.1 localhost13
> 127.0.0.1 localhost14
> 127.0.0.1 localhost15
> This way you can start DataNodes, and TaskTrackers (up to 16 of them) with
> unique hostnames.
> Also, I changed all the places that used to call
> InetAddress.getLocalHost().getHostName() to get it from a new method in
> Configuration (this issue is the same as
> http://issues.apache.org/jira/browse/HADOOP-197 ).
