Mickael Olivier commented on HDFS-6515:
---------------------------------------
The test class that failed because of a timeout seems unreleated to my
modifications as it does not seem to have anything to do with the filesystem. I
cannot retrieve it on Jenkins test results, and on eclipse I see a
TestHttpServer that is in the http package, not the hdfs one.
Other tests that were not skipped seem to path without any failure, but the
console output log is disturbing as there are several weird exceptions. I
wonder weither it is possible to resubmit the patch using -X option or not.
Errors I found are :
hdfsOpenFile(/tlhData0001/file1):
FileSystem#open((Lorg/apache/hadoop/fs/Path;I)Lorg/apache/hadoop/fs/FSDataInputStream;)
error
hdfsOpenFile(/tlhData0002/file1):
FileSystem#open((Lorg/apache/hadoop/fs/Path;I)Lorg/apache/hadoop/fs/FSDataInputStream;)
error
ERROR: cannot open an hdfs file in mode 0x3
java.io.FileNotFoundException: File does not exist: /tlhData0002/file1
ERROR: cannot open an hdfs file in mode 0x3
hdfsOpenFile(/tlhData0000/file1):
FileSystem#open((Lorg/apache/hadoop/fs/Path;I)Lorg/apache/hadoop/fs/FSDataInputStream;)
error
But these might not be what we are looking for.
On the other hand, the only reference to TestHttpServer is :
Running org.apache.hadoop.http.TestHttpServer
When running mvn -Dtest=TestHttpServer test -X on my ubuntu VB, and on my ppc
(RHEL 6.5), it successfully builds on my side.
What kind of environment are you using for testing ?

> Key: HDFS-6515
> URL: https://issues.apache.org/jira/browse/HDFS-6515
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: datanode
> Affects Versions: 3.0.0, 2.4.0
> Environment: Linux on PPC64
> Reporter: Tony Reix
> Priority: Blocker
> Labels: test
> Attachments: HDFS-6515-1.patch
>
>
> I have an issue with test :
> testPageRounder
> (org.apache.hadoop.hdfs.server.datanode.TestFsDatasetCache)
> on Linux/PowerPC.
> On Linux/Intel, test runs fine.
> On Linux/PowerPC, I have:
> testPageRounder(org.apache.hadoop.hdfs.server.datanode.TestFsDatasetCache)
> Time elapsed: 64.037 sec <<< ERROR!
> java.lang.Exception: test timed out after 60000 milliseconds
> Looking at details, I see that some "Failed to cache " messages appear in the
> traces. Only 10 on Intel, but 186 on PPC64.
> On PPC64, it looks like some thread is waiting for something that never
> happens, generating a TimeOut.
> I'm now using IBM JVM, however I've just checked that the issue also appears
> with OpenJDK.
> I'm now using Hadoop latest, however, the issue appeared within Hadoop 2.4.0 .
> I need help for understanding what the test is doing, what traces are
> expected, in order to understand what/where is the root cause.
