Summary: 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: Alejandro Abdelnur Fix For: 2.0.3-alpha 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 is automatically generated by JIRA.
