The error seems to indicate that the create dir/write to HDFS failed. Can you check compare what user you are running as and whether the user has permissions to create/write to the directories in the path below? Furthermore, you may wish to check if the datanodes are alive and also look for errors earlier in the logs to see what failed ( due to the bit related to "Previous writer likely failed” ) .
