Steve Loughran commented on HADOOP-19001:
-----------------------------------------
we've tried to lock this down for security, if you can find any explicit
discussion on what decisions were made with the new scripts, that may show the
reasoning. Or its just an accidental change. See what you can find out before
we rush to change this.
> LD_LIBRARY_PATH is missing HADOOP_COMMON_LIB_NATIVE_DIR
> -------------------------------------------------------
>
> Key: HADOOP-19001
> URL: https://issues.apache.org/jira/browse/HADOOP-19001
> Project: Hadoop Common
> Issue Type: Bug
> Affects Versions: 3.2.4
> Reporter: Zilong Zhu
> Priority: Major
>
> When we run a spark job, we find that it cannot load the native library
> successfully.
> We found a difference between hadoop2 and hadoop3.
> hadoop2-Spark-System Properties：
> |java.library.path|:/hadoop/lib/native:/usr/java/packages/lib/amd64:/usr/lib64:/lib64:/lib:/usr/lib|
> hadoop3-Spark-System Properties：
> |java.library.path|:/usr/java/packages/lib/amd64:/usr/lib64:/lib64:/lib:/usr/lib|
> The key point is：
> hadoop2-hadoop-config.sh：
> HADOOP_OPTS="$HADOOP_OPTS -Djava.library.path=$JAVA_LIBRARY_PATH" <--267
> export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$JAVA_LIBRARY_PATH <--268
>
> hadoop3-hadoop-functions.sh:
> hadoop_add_param HADOOP_OPTS java.library.path \
> "-Djava.library.path=${JAVA_LIBRARY_PATH}"
> export LD_LIBRARY_PATH <--1484
>
> At the same time, the hadoop3 will clear all non-whitelisted environment
> variables.
> I'm not sure if it was intentional. But it makes our spark job unable to find
> the native library on hadoop3.
> Maybe we should modify hadoop-functions.sh(1484) and add LD_LIBRARY_PATH to
> the default configuration item yarn.nodemanager.env-whitelist.
