Bigdata, Hadoop ecosystem, Semantic IoT등의 프로젝트를 진행중에 습득한 내용을 정리하는 곳입니다.
필요한 분을 위해서 공개하고 있습니다.
문의사항은 gooper@gooper.com로 메일을
보내주세요.
1. application실행하면 "YarnApplicationState: ACCEPTED: waiting for AM container to be allocated, launched and register with RM"가 UI에 표시되면서 job이 hang이 걸리면서 진행이 되지 않는 경우가 있는데 그때는 yarn-site.xml의 "yarn.nodemanager.resource.memory-mb"의 값을 매우 크게 지정하여 appliction을 실행하면 hang은 걸리지 않으나 아래의 2번 항목의 문제가 발생한다.
(yarn.nodemanager.vmem-check-enabled, yarn.nodemanager.vmem-pmem-ratio의 설정값이 없는 경우)
2. hadoop application을 실행할때 "Container [pid=19278,containerID=container_1493858350369_0001_01_000008] is running beyond virtual memory limits. Current usage: 636.1 MB of 1 GB physical memory used; 2.4 GB of 2.1 GB virtual memory used. Killing container." 같은 오류가 길생되면서 job이 실패하는 경우가 있는데 이것은 application이 가용한 가상메모리 보다 더 많은 메모리를 사용할때 발생하는 문제이다. 그래서 hadoop이 가상메모리 제한을 체크하지 않도록 하고 많은 메모리를 사용하는 appliction을 위해서 가상메모리와 물리메모리 비율을 높게 설정해 준다.(yarn-site.xml에 설정해줌)
