4. Hadoop streaming jobs issue with WebHCat

Solution:

  1. Check if the file /user/webhcat/hadoop-streaming.jar exists on HDFS:

    su - webhcat
    hadoop dfs -ls /user/webhcat/hadoop-streaming.jar
  2. If the above command fails, copy the Hadoop streaming JAR file:

    su - webhcat
                
    /usr/bin/hadoop --config ${hadoopconfdir} fs -copyFromLocal  /usr/share/hadoop/contrib/streaming/hadoop-streaming*.jar /user/webhcat/hadoop-streaming.jar
