本文详细解析了在启动HadoopResourceManager时遇到的警告信息，包括JDK库加载可能导致的问题及解决方案。通过调整环境变量HADOOP_COMMON_LIB_NATIVE_DIR和HADOOP_OPTS，可以有效避免由库加载引发的stackguard警告。

starting resourcemanager, logging to /opt/hadoop-2.10.0/logs/yarn-liuqiang-resourcemanager-mu01.out
Java HotSpot(TM) Server VM warning: You have loaded library /opt/hadoop-2.10.0/lib/native/libhadoop.so.1.0.0 which might have disabled stack guard. The VM will try to fix the stack guard now.
It's highly recommended that you fix the library with 'execstack -c <libfile>', or link it with '-z noexecstack'.

原因是JDK的库警告

解决方法:

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

参考:https://stackoverflow.com/questions/22006211/hadoop-warning-message-execstack-c-libfile-or-link-it-with-z-noexecsta

确定要放弃本次机会？

强烈建议您使用‘execstack-c’修复该库，或者使用‘-z noexecstack’链接它。JAVA HotSpot(TM)客户端VM警告：您已加载库。它可能已经禁用了堆栈保护。VM现在将尝试修复堆栈保护。
