Hadoop：Mapreduce无法启动/运行

Question

我是Hadoop的新手，请帮助

2019-10-07 18：44：46,563 [main]信息org.apache.pig.backend.hadoop.executionengine.mapReduceLayer.MapReduceLauncher-HadoopJobId：job_1569922894111_0023 2019-10-07 18：44：46,563 [main]信息org.apache.pig.backend.hadoop.executionengine.mapReduceLayer.MapReduceLauncher-处理别名旅行2019-10-07 18：44：46,563 [main] INFO org.apache.pig.backend.hadoop.executionengine.mapReduceLayer.MapReduceLauncher-详细位置：M：trip [1,7]，trip [-1，-1] C：R：2019-10-07 18：44：46,575 [main] INFO org.apache.pig.backend.hadoop.executionengine.mapReduceLayer .MapReduceLauncher-0％完成2019-10-07 18：44：46,575 [main] INFO org.apache.pig.backend.hadoop.executionengine.mapReduceLayer.MapReduceLauncher-正在运行的作业是[job_1569922894111_0023]

这是使用命令“ dump trip”后得到的；我已加载数据并存储在trip中。我猜MapReduce不在运行/启动。
