Error:java heap size
Hi,
I am using hadoop-2.0.0-cdh4.3.0 version (YARN) and when i tried to run a MR job(6gb file) i got yhe following error:
ERROR: java heap size
Plese give me a solution to solve this...

Posted by Devaraj k <de...@huawei.com>.
As you described in the below MR Job uses 6 GB file, how many tasks are there in this Job and how much is the i/p for each task?
Is there any chance of holding more data by tasks in-memory, could you check your map function why it is not able to run with 2GB memory.
Could you also check those failing task log files, you will get more idea who is causing the problem.
Thanks

Hi,
I have set the properties in mapred-site.xml as follows:
<property>
<name>mapreduce.map.memory.mb</name>
<value>2048</value>
</property>
<property>
<name>mapreduce.map.java.opts</name>
<value>-Xmx2048M</value>
</property>
<property>
<name>mapreduce.reduce.memory.mb</name>
<value>2048</value>
</property>
<property>
<name>mapreduce.reduce.java.opts</name>
<value>-Xmx2048M</value>
</property>
But i am still getting the same error in AM logs with some improvement in mapping process.
I have found the property "mapreduce.task.io.sort.mb" set with the value 512. Is there any significance in changing this value to resolve this error?
Thanks,
Ramya

Hi Ramya,
We need to change the –Xmx value for your Job tasks according to the memory allocating for map/reduce containers.
You can pass the –Xmx value for map and reduce yarn child’s using configurations "mapreduce.map.java.opts" and "mapreduce.reduce.java.opts".
If you are allocating 2GB for map container, you can probably pass the same value as –Xmx for the mapreduce.map.java.opts and same way for reducer as well.
Thanks

Could you see the error in client side/RM/AM log? What is the detailed error?

</property>
<property>
<name>mapreduce.reduce.memory.mb</name>
<value>2048</value>
</property>
<property>
<name>mapreduce.reduce.java.opts</name>
<value>-Xmx2048M</value>
</property>
But i am still getting the same error in AM logs with some improvement in mapping process.
I have found the property "mapreduce.task.io.sort.mb" set with the value 512. Is there any significance in changing this value to resolve this error?
Thanks,
Ramya

Hi Ramya,
We need to change the –Xmx value for your Job tasks according to the memory allocating for map/reduce containers.
You can pass the –Xmx value for map and reduce yarn child’s using configurations "mapreduce.map.java.opts" and "mapreduce.reduce.java.opts".
If you are allocating 2GB for map container, you can probably pass the same value as –Xmx for the mapreduce.map.java.opts and same way for reducer as well.
Thanks

Hi Ramya,
Where did you get the java heap size error?
Could you see the error in client side/RM/AM log? What is the detailed error?
