What is the reason of this error and how can I solve this problem?

any help appreciated.

Answer 1

You can see the application logs for the actual issue.

For this you can open the namenode web interface on namenode_ip:50070
Here you can see browse option, click it.
In the submenu, select logs.
Now select the userlogs.

Here you can see the list of applications you ran.

Open the link application_1491779488590_0002 for your above mentioned job inside you can see the logs for each map & reduce task. Open map/reduce job log link.

Inside it you can see: sys, error, stdout files. From these log files you can get the actual error and can fix it.

Or you see these logs in $HADOOP_HOME/logs/userlogs/application_id path.

Application failed 2 times because if application master failed for some reason, by default it will try to execute the application one more time. The AM retry property can be set to 1 to avoid this.
