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
