Map-only job is not running. Stuck at Running job

I have streamed data through Apache Flume and the data has been stored in a temp file in my hdfs folder at: user/*****/tweets/FlumeData.1643626732852.tmp

Now I am trying to run a mapper only job which will be pre-processing the job by way of url removal, # tag removal, @ removal, stop word removal etc.

However, the mapper only job is stopped at Running job.

Mapper job code:

 hadoop jar mr-job-jars/SentimentAnalysisPreprocessingJob.jar com.hadoop.poc.sentimentAnalysis.phase1.SentimentAnalysisPreprocessingDriver /user/*****/tweets/ FlumeData.1643626732852.tmp /output

Execution output:

What do I need to do to solve this problem? Please help. Also, for any added information required please inform me. I will try to provide them as soon as possible.

Adding screenshot of the YARN UI: Yarn UI

Solution

  • Solved my problem by changing the mapreduce.framework.name from yarn to local in mapred-site.xml.

    The problem seemed to be happening due to resource crunch in the machine.

    Also after changing the properties, restart Hadoop services once again.
