I have always seen -Xmx set in megabytes versus gigabytes. It does work
for me on Ubuntu as G but tt may depend on the JVM and OS, -Xmx1024M
version -Xmx1G. Other than that I think it looks good

Hi,
Could you please sanity check this:
In Hadoop-site.xml I add:
<property>
<name>mapred.child.java.opts</name>
<value>-Xmx1G</value>
<description>Increasing the size of the heap to allow for large in
memory index of polygons</description>
</property>
Is this all required to increase the -Xmx for processes running Maps?
(During Mapper.configure() I build a large hashtree lookup object...)
Many thanks
Tim
