hadoop rpm does not create the appropriate link for the native files
--------------------------------------------------------------------
Key: HADOOP-7850
URL: https://issues.apache.org/jira/browse/HADOOP-7850
Project: Hadoop Common
Issue Type: Bug
Affects Versions: 0.20.205.0
Reporter: Arpit Gupta
Assignee: Giridharan Kesavan
hadoop rpm installs the following files
/usr/lib/libhadoop.so
/usr/lib/libhadoop.so.1.0.0
>From the size it looks like the libhadoop.so.1.0.0 points to the 64 bit native
>files
ls -latr /usr/lib/libhadoop.so.1.0.0 /usr/lib/native/Linux-amd64-64/libhadoop.so
-rw-r--r-- 1 root root 177483 Oct 7 06:22
/usr/lib/native/Linux-amd64-64/libhadoop.so
-rw-r--r-- 1 root root 177483 Oct 7 06:25 /usr/lib/libhadoop.so.1.0.0
And the libhadoop.so file points to the 32 bit version
ls -latr /usr/lib/libhadoop.so /usr/lib/native/Linux-i386-32/libhadoop.so
-rw-r--r-- 1 root root 160438 Oct 7 06:20
/usr/lib/native/Linux-i386-32/libhadoop.so
-rw-r--r-- 1 root root 160438 Oct 7 06:20 /usr/lib/libhadoop.so
This causes the 64bit tasktracker to not load the native libraries unless the
libhadoop.so file is linked to the libhadoop.so.1.0.0
