Hello Everyone,
I am new to Hadoop. I have been able to install it successfully. As a next
step I have been trying to build the hadoop common from eclipse but running
into some compile errors. Here is what I have done so far:
1. Cloned the git repository from git://github.com/apache/hadoop-common.git
2. I am using Eclipse 3.6 on Max OS X 10.6.5.
3. Set the ANT_HOME in Eclipse to point to the ant directory in
eclipse/plugins..
4. Disabled "Build Automatically"
5. On build.xml perform Run As -> Ant Build
6. In the targets select compile, eclipse, compile-core-test
7. Compilation fails while running the compile-core-test with the following
error (tried with both the 0.21 as well as the trunk):
