Aaron T. Myers commented on HADOOP-8884:
----------------------------------------
Great point, Todd. I should've thought of that.
It doesn't actually happen for every `hadoop fs -ls' operation per se, since
that doesn't try to load the native libs, but it will happen for any command
that would try to do so, e.g. `hadoop fs -cat':
{noformat}
$ hadoop fs -cat bashrc
12/10/08 14:17:27 WARN util.NativeCodeLoader: Continuing after failing to load
native-hadoop -
java.library.path=/home/atm/Downloads/jdk1.6.0_30/jre/lib/amd64/server:/home/atm/Downloads/jdk1.6.0_30/jre/lib/amd64:/home/atm/Downloads/jdk1.6.0_30/jre/../lib/amd64:/usr/local/lib:/usr/java/packages/lib/amd64:/usr/lib64:/lib64:/lib:/usr/lib
with error:
java.lang.UnsatisfiedLinkError: no hadoop in java.library.path
{noformat}
I'll go ahead and revert this commit for now. Perhaps we should try to find a
way to print this warning only when the native libs fail to load for some
reason other than them being not present entirely.
