Alejandro Abdelnur reassigned YARN-160: --------------------------------------- Assignee: (was: Alejandro Abdelnur) I have my hands full at the moment, I won't be able to take onto this one for a while. Making it unassigned in case somebody wants to take a stab to it. > 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 > Fix For: 2.1.0-beta > > > 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.
