The number of map/reduce task attempt slots presented by a TaskTracker is set at the time the TaskTracker starts, and is controlled via two settings in mapred-site.xml on each node: mapred.tasktracker.map.tasks.maximum But I get a Java heap space error, can someone help me ?
Jaxb Unmarshal Large Xml Files
What can I do to prevent this in the future? So, configure you JVM heap to 1 - 2 G and forget continue your development. (use -Xmx1G) command line option when running JVM. You serialize object into XML using JAXB that uses DOM.

There are a few additional issues to be aware of when managing task attempt memory. Why don't you marshal to a file? –laune Oct 12 '15 at 6:50 @ShekharKhairnar what do you expect from this post - what is your question? it works now. JAXB will then advance the XMLStreamReader to the end of that element.

Check that the JVMs settings are suitable for your tasks.
Typically for large documents I recommend people leverage a StAX XMLStreamReader so that the document can be unmarshalled by JAXB in chunks. share|improve this answer answered Feb 15 '15 at 15:36 AmitB 115 While this link may answer the question, it is better to include the essential parts of the answer Outer Tie-rod removal Enable Wireless on Fresh Debian Build How to encourage 2 year old to co-operate Why is the size of my email so much bigger than the size of have a peek at these guys BTW: make sure that when your serializing the object you marshal it directly to file (or web resource or other external target) and not to byte array or string.

The only way to solve other then increasing the heap space is to see what is using all the heap space and then trying to make sure objects can be collected It’s a safe solution, as the nodes shouldn't start paging aggressively, it’s an easy solution since it doesn’t require a lot of memory calculations, and it’s fast since the solution requires
