Error reason: the size of the job.splitmetainfo file of this job exceeds the limit

1. Job.splitmetadata info, which records metadata information of split, job split —– > HDFS block && amp; slave node

  The storage path is located at ${Hadoop. TMP. Dir}/mapred/staging/${user. Name} /. Staging/jobid/

2. The parameter mapreduce.jobtracker.split.metainfo.maxsize controls the maximum size of the file. The default is 10000000 (10m)
