I’m trying to schedule an oozie job to run 2 sqoop action concurrently using fork in sandbox. Previously when I run in Hadoop 1 sandbox, I faced the oozie deadlock issue (where by 2 sqoop jobs hang there and it keep display “Heart beat” and the job will never end) but I am able to fixed it by apply the below settings.
mapred.tasktracker.map.tasks.maximum = 4
mapred.tasktracker.reduce.tasks.maximum = 4
Now, when I tried the same oozie job in Hadoop 2 (YARN) sandbox, i faced the same deadlock issue again. However, after I tried to apply the below setting, the problem still exists.
mapreduce.map.cpu.vcores = 4
mapreduce.reduce.cpu.vcores = 4
Anyone could shed me some light? Appreciate your help. Thanks.
