Hrishikesh commented on HADOOP-1773:
------------------------------------
Hi Yuri,
Can you try this out ...
Say you have a directory abc physically present on a machine X and you have
exported this directory
On machine Y you mount the abc directory on a mount point /mnt/testtouch
The you login to machine Y as a normal user (who shall be firing the hadoop)
build and then try to touch files /mnt/testtouch using the unix touch command ?
IMO when touching files on a NFS share, the "modified time" will need to be
changed in the file system of the machine which physically holds the files (and
may be thats causing the blockage)
Also can you try the build on the machine which physically holds the files
(i.e. the machine from which the NFS share is exported) ?

> Key: HADOOP-1773
> URL: https://issues.apache.org/jira/browse/HADOOP-1773
> Project: Hadoop
> Issue Type: Bug
> Components: build
> Affects Versions: 0.15.0
> Environment: Fedora7 on x64, java version "1.6.0_02", latest hadoop
> (svn version as of 8/21/07), ant version 1.7.0 (but same problem with 1.6.5)
> Reporter: Yuri Pradkin
> Priority: Critical
>
> Ant hangs during a build process, eventually (in hours) dies of heap
> exhaustion.
> The problematic lines in build.xml seem to be in the init target (fileset
> operations):
> - <touch datetime="01/25/1971 2:00 pm">
> - <fileset dir="${conf.dir}" includes="**/*.template"/>
> - <fileset dir="${contrib.dir}" includes="**/*.template"/>
> - </touch>
> - <copy todir="${conf.dir}" verbose="true">
> - <fileset dir="${conf.dir}" includes="**/*.template"/>
> - <mapper type="glob" from="*.template" to="*"/>
> - </copy>
> - <copy todir="${contrib.dir}" verbose="true">
> - <fileset dir="${contrib.dir}" includes="**/*.template"/>
> - <mapper type="glob" from="*.template" to="*"/>
> - </copy>
> Commenting them out or deleting allows build to proceed to sucessful
> completion. Not being an expert,
> in either xml or ant, I'm not sure what exactly I'm missing with those lines
> gone, but at least I'm able to compile.
