I tried using the mapper with namespace entities. The mapper fails to run and complains
com.google.appengine.tools.mapreduce.MapReduceServlet handleCommand: Got exception while running command java.lang.RuntimeException: Got an IOException while trying to make splits Caused by: java.io.IOException: No entities in the datastore query to split. Any ways to configure the mapper for working with all namespaces? -Aswath On Mon, May 16, 2011 at 10:18 PM, Stephen Johnson <[email protected]>wrote: > I have two questions on the Java version of mapreduce since the docs seem > pretty sparse. > 1.)
