Change to nodemanager build now requires 32-bit libraries
---------------------------------------------------------
Key: HADOOP-8099
URL: https://issues.apache.org/jira/browse/HADOOP-8099
Project: Hadoop Common
Issue Type: Bug
Affects Versions: 0.23.0
Environment: Centos 6, x86_64
Reporter: Ralph H Castain
Sometime during the last week, someone committed a change to:
hadoop-mapreduce-project/hadoop-yarn/hadoop-yarn-server/hadoop-yarn-server-nodemanager/pom.xml
that inserted a -m32 in:
<configureEnvironment>
<property>
<name>CFLAGS</name>
<value>-DHADOOP_CONF_DIR=${container-executor.conf.dir}
-m32</value>
This breaks the build on 64-bit systems that do not have 32-bit libraries
installed. The change was actually not required as 64-bit support for JNI and
JVMs is readily available and installed by default on many 64-bit systems.
Removing the flag results in a completed and functional build.
If mandating 32-bit builds is desired, then a better solution would be to
provide a configure flag such as -DHADOOP_32bit_MODE, perhaps with a
corresponding flag for 64-bit. Regardless, locking the system to 32-bit builds
seems a tad extreme.
