问题
After installing a new Hadoop cluster using Ambari, I tried to submit a mapreduce job, but it failed throwing an error.
Error:
java.io.FileNotFoundException: File does not exist: hdfs://xx-xx-xxx-x:8020/hdp/apps/2.2.9.0-3393/mapreduce/mapreduce.tar.gz
回答1:
Issue resolved after restarting all components from Ambari UI.
