I tried to run WordCount.jar file to experience running hadoop jobs. After launching the program as shown in the screenshot below, I have the message in the screenshot. The job tries to connect to the datanode. But failed after 10 attempts, I got the error in the second screenshot. After that, I first stop all the Hadoop deamons, second format the dfs, third re-launch Hadoop deamons, and I notice using the JPS command that DATANODE is not running. I then run the datanode alone with the command bin/hadoop –deamon.sh start datanode as shown in the third screenshot, but the datanode is still not up and running. Could someone advice in this case, please ? Standing by for your habitual support. Thank in advance.
