Hudson commented on YARN-782: ----------------------------- Integrated in Hadoop-Hdfs-trunk #1431 (See [https://builds.apache.org/job/Hadoop-Hdfs-trunk/1431/]) YARN-782. vcores-pcores ratio functions differently from vmem-pmem ratio in misleading way. (sandyr via tucu) (Revision 1493064) Result = FAILURE tucu : http://svn.apache.org/viewcvs.cgi/?root=Apache-SVN&view=rev&rev=1493064 Files : * /hadoop/common/trunk/hadoop-yarn-project/CHANGES.txt * /hadoop/common/trunk/hadoop-yarn-project/hadoop-yarn/hadoop-yarn-api/src/main/java/org/apache/hadoop/yarn/conf/YarnConfiguration.java * /hadoop/common/trunk/hadoop-yarn-project/hadoop-yarn/hadoop-yarn-common/src/main/resources/yarn-default.xml * /hadoop/common/trunk/hadoop-yarn-project/hadoop-yarn/hadoop-yarn-server/hadoop-yarn-server-nodemanager/src/main/java/org/apache/hadoop/yarn/server/nodemanager/NodeStatusUpdaterImpl.java > vcores-pcores ratio functions differently from vmem-pmem ratio in misleading > way > --------------------------------------------------------------------------------- > > Key: YARN-782 > URL: https://issues.apache.org/jira/browse/YARN-782 > Project: Hadoop YARN > Issue Type: Improvement > Components: nodemanager > Affects Versions: 2.0.4-alpha > Reporter: Sandy Ryza > Assignee: Sandy Ryza > Priority: Critical > Fix For: 2.1.0-beta > > Attachments: YARN-782-1.patch, YARN-782.patch > > > The vcores-pcores ratio functions differently from the vmem-pmem ratio in the > sense that the vcores-pcores ratio has an impact on allocations and the > vmem-pmem ratio does not. > If I double my vmem-pmem ratio, the only change that occurs is that my > containers, after being scheduled, are less likely to be killed for using too > much virtual memory. But if I double my vcore-pcore ratio, my nodes will > appear to the ResourceManager to contain double the amount of CPU space, > which will affect scheduling decisions. > The lack of consistency will exacerbate the already difficult problem of > resource configuration. -- This message is automatically generated by JIRA.
