我正在使用 docker-spark .启动spark-shell后，输出:

15/05/21 04:28:22 DEBUG NativeCodeLoader: Failed to load native-hadoop with error: java.lang.UnsatisfiedLinkError:no hadoop in java.library.path
15/05/21 04:28:22 DEBUG NativeCodeLoader: java.library.path=/usr/java/packages/lib/amd64:/usr/lib64:/lib64:/lib:/usr/lib

这个spark容器的环境变量是:

bash-4.1# export
declare -x BOOTSTRAP="/etc/bootstrap.sh"
declare -x HADOOP_COMMON_HOME="/usr/local/hadoop"
declare -x HADOOP_CONF_DIR="/usr/local/hadoop/etc/hadoop"
declare -x HADOOP_HDFS_HOME="/usr/local/hadoop"
declare -x HADOOP_MAPRED_HOME="/usr/local/hadoop"
declare -x HADOOP_PREFIX="/usr/local/hadoop"
declare -x HADOOP_YARN_HOME="/usr/local/hadoop"
declare -x HOME="/"
declare -x HOSTNAME="sandbox"
declare -x JAVA_HOME="/usr/java/default"
declare -x OLDPWD
declare -x PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/java/default/bin:/usr/local/spark/bin:/usr/local/hadoop/bin"
declare -x PWD="/"
declare -x SHLVL="3"
declare -x SPARK_HOME="/usr/local/spark"
declare -x SPARK_JAR="hdfs:///spark/spark-assembly-1.3.0-hadoop2.4.0.jar"
declare -x TERM="xterm"
declare -x YARN_CONF_DIR="/usr/local/hadoop/etc/hadoop"

引用后Hadoop “Unable to load native-hadoop library for your platform” error on CentOS ，我做了以下事情:

(1)检查hadoop库:

bash-4.1# file /usr/local/hadoop/lib/native/libhadoop.so.1.1.0
/usr/local/hadoop/lib/native/libhadoop.so.1.0.0: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked, not stripped

是的，它是64位库。

(2) 尝试添加 HADOOP_OPTS 环境变量:

export HADOOP_OPTS="$HADOOP_OPTS -Djava.library.path=/usr/local/hadoop/lib/native"

不行，报同样的错误。

(3) 尝试添加 HADOOP_OPTS 和 HADOOP_COMMON_LIB_NATIVE_DIR 环境变量:

export HADOOP_COMMON_LIB_NATIVE_DIR=$HADOOP_HOME/lib/native
export HADOOP_OPTS="-Djava.library.path=$HADOOP_HOME/lib"

还是不行，报同样的错误。

谁能提供一些关于这个问题的线索？

最佳答案

将 Hadoop 库添加到 LD_LIBRARY_PATH 修复此问题:

export LD_LIBRARY_PATH="$HADOOP_HOME/lib/native/:$LD_LIBRARY_PATH"
