Question

I m trying to run some hadoop program to extracting keywords of some abstracts in Ubuntu. When I run my program using Hadoop, I get the following error.

 WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable

What s the cause of this error?

Note that I converted my mapreduce project to maven project for using lucene library in my code.

Answer 1

Is your resource manager really on the /0.0.0.0:8032? It also seams you are not using Toolrunner, so try to rewrite your mapreduce Hadoop: Implementing the Tool interface for MapReduce driver.

Hope it helps

Answer 2

Number of thread increased, JVM memory and CPU is fully utilised. Please increase the JVM size and increase memory limit of Mapper and reducer task. conf.set("mapreduce.map.memory.mb", "4096"); conf.set("mapreduce.map.java.opts", "-Xmx3500m");
