It seems HADOOP_CONF_DIR is poiniting different location!!?
May be you can check hdfs-site.xml is in classpath when you execute hdfs co=
mmand.


Thanks & Regards

Subject: Change the blocksize in 2.5.1

Hello everyone,

I've just installed Hadoop 2.5.1 from source code, and I have problems chan=
ging the default block size. My hdfs-site.xml file I've set the property

  <property>
     <name>dfs.blocksize</name>
     <value>67108864</value>
  </property>

to have blocks of 64 MB, but it seems that the system ignore this setting. =
When I copy a new file, it uses a block size of 128M. Only if I specify the=
 block size when the file is created (ie hdfs dfs
-Ddfs.blocksize=3D$((64*1024*1024)) -put file .) it uses a block size of
64 MB.

Any idea?

Best regards

Tomas
