alluxio on hdfs :native-hadoop library

ge zhang

Hi guys,
I run alluxio cluster on hadoop_2.6.0.After I use shell  commond  persist to persist a file on hdfs, then I use cat to read the file on underFS-----hdfs. I can read the file successfully. However in the usr.log , there is  a WARN. I show it below.

Can anyone help?
Best,
Ge

This is a warning due to the native Hadoop library cross-platform.
I think you will also see this WARNING if you directly access your HDFS with hadoop shell.

You can see here for details:

Hope this helps,

Hi chaomin,
  That is strange, because I don't see the same warn in hadoop, and I have already compile the 64-bit hadoop.
