Error and problem when running a hadoop job
Hello Dear hadoopers,
I hope you are doing well.
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.

RE: Error and problem when running a hadoop job
Posted by YIMEN YIMGA Gael <ga...@sgcib.com>.
Hi,
When I run the following command to launch DATANODE as shown in the screenshot below, all is ok
But when I run JPS command, I do not see the datanode process
[cid:image004.png@01CFCC5C.E98838B0]
That’s where my worry is ☹ ☹

Hello Dear hadoopers,
I hope you are doing well.
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 ?

Hello Dear hadoopers,
I hope you are doing well.
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.
