1.spark启动参数
先把log4j配置文件放到hdfs:hdfs://R2/projects/log4j-debug.properties
--conf spark.yarn.dist.files=hdfs://R2/projects/log4j-debug.properties#log4j-first.properties \
--conf "spark.driver.extraJavaOptions=-Dlog4j.configuration=file:log4j-first.properties" \
--conf "spark.executor.extraJavaOptions=-XX:+PrintGCDetails -XX:+PrintGCTimeStamps -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=/tmp/heapdump.hprof -Dlog4j.configuration=file:log4j-first.properties" \
