Minor Description
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.
