---------------------------------

What's new about this issue ?
I've seen that some changes were made in 18.0-Snapshot.

>                 Key: AVRO-1567
>                 URL: https://issues.apache.org/jira/browse/AVRO-1567
>             Project: Avro
>          Issue Type: Bug
>          Components: java
>    Affects Versions: 1.7.4, 1.7.7
>         Environment: RHEL 6.5 on x86_64
> IBM JVM 7.1.1.1
> HADOOP 2.4.1
>            Reporter: Tony Reix
>            Priority: Blocker
>   Original Estimate: 1h
>  Remaining Estimate: 1h

> When using IBM JVM, compared to Oracle JVM, 25 of the Avro Tools tests fail.
> This is due to Avro using Hadoop which uses class:
>    org/apache/hadoop/security/UserGroupInformation.java
> which makes use of:
>    com.sun.security.auth.module.UnixLoginModule
> which does not exist in IBM JVM.
> Instead there is the class:
>    com.ibm.security.auth.module.LinuxLoginModule
> that can be used in UserGroupInformation.java if the JVM is IBM.
> With a IBM-JVM patched version of Hadoop that takes care of the kind of JVM, these 25
Avro Java Tools tests still fail because the pom.xml file of:
>     lang/java/tools/
> says unconditionnaly (starting line 146 in Avro 1.7.7) :
>       <dependency>
>       <groupId>org.apache.hadoop</groupId>
>       <artifactId>hadoop-core</artifactId>
> Using:
>   mvn -Phadoop2 -Dhadoop.version=2 test
> is of no help.
> In fact, hadoop-core exists only for old Hadoop versions (here version 0.20.205.0 is
used by Avro), and not for Hadoop 2.4.1 .
> Replacing hadoop-core by hadoop-client in lang/java/tools/pom.xml file does fix the issue,
as a work-around.
> However, a more rigorous solution is required, like it is done in lang/java/mapred/pom.xm
, where hadoop-core is associated with hadoop1 and hadoop-client is associated with hadoop2
.
> I'm not an expert of Maven/pom.xml, and the pom.xml file of tools contains <exclusions>
tags I have no idea. So, I'm not sure I can provide a correct patch.
> I guess that a Maven/pom.xml expert should be able to fix this in some minutes, plus
testing.
