DNS pre request for hadoop install

+1 vote
251 views

I am trying to use ambari (hortonwoks) to install hadoop. One step is to pre-config DNS as manual link below. http://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.0.9.1/bk_using_Ambari_book/content/ambari-chap1-5-5.html

Since I am only using internal network, not sure how to config fully.qualified.domain.name. My hostname -f only shows localhost. And in /etc/sysconfig/network, it give HOSTNAME=localhost.localdomain

If anyone already get hadoop running, what is the real DNS requests for hadoop. Any suggestion, thanks a lot.

How to install Snappy for Hadoop

I am running on Hadoop 1.0.4 and I would like to use Snappy for map output compression. I am adding the configurations:

configuration.setBoolean("mapred.compress.map.output", true);
 configuration.set("mapred.map.output.compression.codec", "org.apache.hadoop.io.compress.SnappyCodec");

And Ive added libsnappy.so.1 to $HADOOP_HOME/lib/native/Linux-amd64-64/
Still, all map tasks fail with "native snappy library not available". Could anyone elaborate on how to install Snappy for Hadoop ?
