Varun Vasudev commented on YARN-160: ------------------------------------ The test failure is unrelated to the patch. > nodemanagers should obtain cpu/memory values from underlying OS > --------------------------------------------------------------- > > Key: YARN-160 > URL: https://issues.apache.org/jira/browse/YARN-160 > Project: Hadoop YARN > Issue Type: Improvement > Components: nodemanager > Affects Versions: 2.0.3-alpha > Reporter: Alejandro Abdelnur > Assignee: Varun Vasudev > Labels: BB2015-05-TBR > Attachments: YARN-160.005.patch, YARN-160.006.patch, > YARN-160.007.patch, apache-yarn-160.0.patch, apache-yarn-160.1.patch, > apache-yarn-160.2.patch, apache-yarn-160.3.patch > > > As mentioned in YARN-2 > *NM memory and CPU configs* > Currently these values are coming from the config of the NM, we should be > able to obtain those values from the OS (ie, in the case of Linux from > /proc/meminfo & /proc/cpuinfo). As this is highly OS dependent we should have > an interface that obtains this information. In addition implementations of > this interface should be able to specify a mem/cpu offset (amount of mem/cpu > not to be avail as YARN resource), this would allow to reserve mem/cpu for > the OS and other services outside of YARN containers. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
