##查看文件是否有系统一致 [root@hadoop1 native]# file /opt/hadoop/lib/native/libhadoop.so.1.0.0 libhadoop.so.1.0.0: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked, not stripped
[hadoop@hadoop2 sbin]$ uname -i
x86_64
给hadoop执行操作了debug，还是没看到详细日志
一开始执行网上的这些操作步骤
vim /opt/hadoop/etc/hadoop/hadoop-env.sh vim /etc/profile export HADOOP_HOME=/opt/hadoop/ export HADOOP_COMMON_LIB_NATIVE_DIR=$HADOOP_HOME/lib/native export HADOOP_OPTS="-Djava.library.path=$HADOOP_HOME/lib:$HADOOP_COMMON_LIB_NATIVE_DIR" source /etc/profile vim ~/.bashrc source ~/.bashrc
完成之后还是报错
于是开始执行
[root@hadoop1 build]# strings /lib64/libc.so.6 | grep GLIBC GLIBC_2.2.5 GLIBC_2.2.6 GLIBC_2.3 GLIBC_2.3.2 GLIBC_2.3.3 GLIBC_2.3.4 GLIBC_2.4 GLIBC_2.5 GLIBC_2.6 GLIBC_2.7 GLIBC_2.8 GLIBC_2.9 GLIBC_2.10 GLIBC_2.11 GLIBC_2.12 GLIBC_PRIVATE
