Subject [jira] [Commented] (HDFS-4629) Using com.sun.org.apache.xml.internal.serialize.* in XmlEditsVisitor.java is JVM vendor specific. Breaks IBM JAVA
Date Sat, 14 Jun 2014 06:32:02 GMT

    [ https://issues.apache.org/jira/browse/HDFS-4629?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14031489#comment-14031489
] 

pascal oliva commented on HDFS-4629:
------------------------------------

No, there wasn't a dependency on xerces .

With IBM JVM the build works fine without xerces dependency in the pom.xml

But by using OpenJDK
i have got the following errors :
[ERROR] /home/pascal/patchI/hadoop-common/hadoop-hdfs-project/hadoop-hdfs/src/main/java/org/apache/hadoop/hdfs/tools/offlineEditsViewer/XmlEditsVisitor.java:[33,31]
 error: package org.apache.xml.serialize does not exist
 [ERROR] /home/pascal/patchI/hadoop-common/hadoop-hdfs-project/hadoop-hdfs/src/main/java/org/apache/hadoop/hdfs/tools/offlineEditsViewer/XmlEditsVisitor.java:[55,4]
error: cannot find symbol
[ERROR]   symbol:   class OutputFormat
  location: class XmlEditsVisitor

And by adding :
+ <groupId>xerces</groupId>
 + <artifactId>xercesImpl</artifactId>
 + <version>2.9.0</version>
 + </dependency>

The build passed successfully with the both JVM : IBM and OpenJDK

To test the patch, I used :
mvn compile ; mvn test -fn
There is no new functionnality delivered on that patch, so i used the existing tests.
