Allen,
I changed it back to the way it was. This is Cloudera's 0.20.2+228 release.
[r...@namenode] # pwd
/opt/hadoop/lib/native/Linux-amd64-64
[r...@namenode] # ls -l libhadoop.*
-rw-rw-r-- 1 root Wheel 117464 2010-03-21 23:15 libhadoop.a
-rw-rw-r-- 1 root Wheel 864 2010-03-21 23:15 libhadoop.la
-rw-rw-r-- 1 root Wheel 77616 2010-03-21 23:15 libhadoop.so
-rw-rw-r-- 1 root Wheel 77616 2010-03-21 23:15 libhadoop.so.1
-rwxr-xr-x 1 root Wheel 77616 2010-03-21 23:15 libhadoop.so.1.0.0
[r...@namenode] # ldd libhadoop.so.1.0.0
./libhadoop.so.1.0.0: /lib64/tls/libc.so.6: version `GLIBC_2.4' not found
(required by ./libhadoop.so.1.0.0)
libjvm.so => not found
libdl.so.2 => /lib64/libdl.so.2 (0x0000002a9578e000)
libc.so.6 => /lib64/tls/libc.so.6 (0x0000002a95891000)
/lib64/ld-linux-x86-64.so.2 (0x000000552aaaa000)
So I'm still confused.
What do I need to do to have hadoop use "native"
(I'm assuming native means the OS's .so files)
for zlib com/de-compression?
Alan
