问题在于Starting namenodes on [Java HotSpot(TM) 64-Bit Server VM warning: You have loaded library /home/grid/hadoop-2.2.0/lib/native/libhadoop.so.1.0.0 which might have disabled stack guard. The VM will try to fix the stack guard now.
还是本地库的问题
我也没遇到过这样的问题，搜索了一下可以试试添加环境变量
export HADOOP_COMMON_LIB_NATIVE_DIR=${HADOOP_PREFIX}/lib/native
export HADOOP_OPTS="-Djava.library.path=$HADOOP_PREFIX/lib"
不一定能完全匹配上，但是个可以尝试的思路
