I have 7 nodes in my Hadoop cluster [8GB RAM and 4VCPUs to each nodes], 1 Namenode + 6 datanodes.
I followed the link o horton works [ http://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.0.6.0/bk_installing_manually_book/content/rpm-chap1-11.html] and made calculation according to the hardware configruation on my nodes and have added the update mapred-site and yarn-site.xml files in my question. Still my application is crashing with the same exection My mapreduce application has 34 input splits with a block size of 128MB. **mapred-site.xml** has the following properties: mapreduce.framework.name = yarn mapred.child.java.opts = -Xmx2048m mapreduce.map.memory.mb = 4096 mapreduce.map.java.opts = -Xmx2048m **yarn-site.xml** has the following properties: yarn.resourcemanager.hostname = hadoop-master yarn.nodemanager.aux-services = mapreduce_shuffle yarn.nodemanager.resource.memory-mb = 6144 yarn.scheduler.minimum-allocation-mb = 2048 yarn.scheduler.maximum-allocation-mb = 6144 Exception from container-launch: ExitCodeException exitCode=134: /bin/bash: line 1: 3876 Aborted (core dumped) /usr/lib/jvm/java-7-openjdk-amd64/bin/java -Djava.net.preferIPv4Stack=true -Dhadoop.metrics.log.level=WARN -Xmx8192m -Djava.io.tmpdir=/tmp/hadoop-ubuntu/nm-local-dir/usercache/ubuntu/appcache/application_1424264025191_0002/container_1424264025191_0002_01_000011/tmp -Dlog4j.configuration=container-log4j.properties -Dyarn.app.container.log.dir=/home/ubuntu/hadoop/logs/userlogs/application_1424264025191_0002/container_1424264025191_0002_01_000011 -Dyarn.app.container.log.filesize=0 -Dhadoop.root.logger=INFO,CLA org.apache.hadoop.mapred.YarnChild 192.168.0.12 50842 attempt_1424264025191_0002_m_000005_0 11 > /home/ubuntu/hadoop/logs/userlogs/application_1424264025191_0002/container_1424264025191_0002_01_000011/stdout 2> /home/ubuntu/hadoop/logs/userlogs/application_1424264025191_0002/container_1424264025191_0002_01_000011/stderr How can avoid this?any help is appreciated Is there an option to restrict number of containers on hadoop ndoes?
