Hello:
I have successfully built Harmony 6 (rev. 1022139) on a SUSE Linux
Enterprise Server 11 using gcc version 4.3.2. I am currently trying to
build the Apache Hadoop component (v. 0.21.0) using Harmony; after some
modifications I am still getting some errors stating that "The type <x> is
already defined" where x is the name of a class. I have tested this using
SUN and IBM JDK's and have had no issues. I wanted to know if this is a
known issue as I could not find anything related in Apache JIRA.
Following, are a series of errors and fixes (provided by Charles Li), while
trying to build the Apache Hadoop common subproject:
BUILD FAILED

following error occurred while executing this line:

com.sun.tools.javac.Main is not on the classpath.
Perhaps JAVA_HOME does not point to the JDK.

The type package-info is already defined
It is worth mentioning that the Hadoop common project has 12
package-info.java files but under different directories/packages.
Thanks,
