问题点：

遇到问题不要慌，仔细看报错，“Diagnostics:…” 错误很明显的
File file:/root/.flink/application_1585641509397_0005/lib/slf4j-log4j12-1.7.15.jar does not exist
在安装Hadoop集群的时候，没有将HADOOP_HOME导出

export HADOOP_HOME=/app/hadoop-2.6.4
export PATH=$JAVA_HOME/bin:$HADOOP_HOME/bin:$PATH
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$HADOOP_HOME/bin:$HADOOP_HOME/sbin

加上这个导出，就可以了
