It should not matter what the process is doing, since if it ignores the SIGTERM then the subsequent SIGKILL will kill it. Unlike SIGTERM, SIGKILL is not catchable by the receiving process. Could you elaborate a bit more on how GC activity is involved? > Now container kill mechanism may lead process leak > -------------------------------------------------- > > Key: YARN-6276 > URL: https://issues.apache.org/jira/browse/YARN-6276 > Project: Hadoop YARN > Issue Type: Improvement > Components: nodemanager > Affects Versions: 3.0.0-alpha2 > Reporter: Feng Yuan > Assignee: Feng Yuan > > When kill bash process, YarnChild may didn`t response because fullgc, -- This message was sent by Atlassian JIRA (v6.3.15#6346) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscribe@hadoop.apache.org For additional commands, e-mail: yarn-issues-help@hadoop.apache.org
