[jira] [Created] (HADOOP-7825) Hadoop wrapper script not picking up
native libs correctly
Hadoop wrapper script not picking up native libs correctly
----------------------------------------------------------
Key: HADOOP-7825
URL: https://issues.apache.org/jira/browse/HADOOP-7825
Project: Hadoop Common
Issue Type: Bug
Components: scripts
Affects Versions: 0.20.205.0
Environment: Debian 6.0 x64_64
java version "1.6.0_26"
Java(TM) SE Runtime Environment (build 1.6.0_26-b03)
Java HotSpot(TM) 64-Bit Server VM (build 20.1-b02, mixed mode)
Reporter: stephen mulcahy
Originally discussed in https://mail-archives.apache.org/mod_mbox/hadoop-common-user/201111.mbox/%3C4EC3A3AE.7060402%40deri.org%3E
I'm testing out native lib support on our test amd64 test cluster
running 0.20.205 running the following
./bin/hadoop jar hadoop-test-0.20.205.0.jar testsequencefile -seed 0
-count 1000 -compressType RECORD xxx -codec
org.apache.hadoop.io.compress.GzipCodec -check 2
it fails with
WARN util.NativeCodeLoader: Unable to load native-hadoop library for
your platform... using builtin-java classes where applicable
Looking at
bin/hadoop
it seems to successfully detect that the native libs are available (they
seem to come pre-compiled with 0.20.205 which is nice)
if [ -d "${HADOOP_HOME}/lib/native" ]; then
if [ "x$JAVA_LIBRARY_PATH" != "x" ]; then
JAVA_LIBRARY_PATH=${JAVA_LIBRARY_PATH}:${HADOOP_HOME}/lib/native/${JAVA_PLATFORM}
else
JAVA_LIBRARY_PATH=${HADOOP_HOME}/lib/native/${JAVA_PLATFORM}
fi
fi
and sets JAVA_LIBRARY_PATH to contain them.
Then in the following line, if ${HADOOP_HOME}/lib contains libhadoop.a
(which is seems to in the stock tar) then it proceeds to ignore the
native libs
if [ -e "${HADOOP_PREFIX}/lib/libhadoop.a" ]; then
JAVA_LIBRARY_PATH=${HADOOP_PREFIX}/lib
fi
The libhadoop.a in ${HADOOP_HOME}/lib seems to be a copy of the lib/native/Linux-i386-32 going from the filesizes (and also noted by https://mail-archives.apache.org/mod_mbox/hadoop-common-user/201111.mbox/%3CCAOcnVr2AzUDnN0LFhmTqUmAyujYtvhfkmMm_J0R-bmxw2wU+9A@mail.gmail.com%3E)
hadoop@testhbase01:~$ ls -la hadoop/lib/libhadoop.*
-rw-r--r-- 1 hadoop hadoop 237244 Oct 7 08:20 hadoop/lib/libhadoop.a

-rw-r--r-- 1 hadoop hadoop 160438 Oct 7 08:19 hadoop/lib/libhadoop.so.1.0.0
hadoop@testhbase01:~$ ls -la hadoop/lib/native/Linux-i386-32/
total 728
drwxr-xr-x 3 hadoop hadoop 4096 Nov 15 14:05 .
drwxr-xr-x 5 hadoop hadoop 4096 Oct 7 08:24 ..
-rw-r--r-- 1 hadoop hadoop 237244 Oct 7 08:20 libhadoop.a
-rw-r--r-- 1 hadoop hadoop 877 Oct 7 08:20 libhadoop.la

-rw-r--r-- 1 hadoop hadoop 160438 Oct 7 08:20 libhadoop.so.1.0.0
A possible solution includes removing libhadoop.a and friends from ${HADOOP_HOME}/lib and possibly also modifying the hadoop wrapper to remove
if [ -e "${HADOOP_PREFIX}/lib/libhadoop.a" ]; then
JAVA_LIBRARY_PATH=${HADOOP_PREFIX}/lib
fi
unless there is some other reason for this to exist.

[jira] [Commented] (HADOOP-7825) Hadoop wrapper script not picking
up native libs correctly
Posted by "Harsh J (Commented) (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/HADOOP-7825?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13151822#comment-13151822 ]
Harsh J commented on HADOOP-7825:
---------------------------------
Two things I'll need to investigate here before proposing to remove such a check:
- What are native libs doing in lib/, when you can't guarantee their platform/arch without using external tools?
- What utilizes their presence in lib/ in 205 today.
Clearly, using 'file', tells you that those under lib/* are 32-bit binaries in the tar we ship today. This breaks native code loading in all 64-bit deployments.
