spark集群部署错误告警随记

1，Error: Could not find or load main class namenode-format

这个是错误的把hadoop namenode -format 命令写成hadoop namenode-format

2,  WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable

在/etc/profile中加上这两句

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