Recently we observed that YARN is using 2000% of the memory. </P><P>Currently we allocated 2GB for yarn memory and the metrics showed 40GB was used for our current job. All nodes are still "alive". Will that be a problem? Should we increase the allocated memory for yarn cluster?</P><P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="2178-ambari-elephant2-1.png" style="width: 1700px;"><img src="https://community.cloudera.com/t5/image/serverpage/image-id/21571iC7A61D811B59DD17/image-size/medium?v=v2&amp;px=400" role="button" title="2178-ambari-elephant2-1.png" alt="2178-ambari-elephant2-1.png" /></span></P><P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="2179-ambari-elephant-1.png" style="width: 1700px;"><img src="https://community.cloudera.com/t5/image/serverpage/image-id/21572i92C993BCD3F83B31/image-size/medium?v=v2&amp;px=400" role="button" title="2179-ambari-elephant-1.png" alt="2179-ambari-elephant-1.png" /></span></P> Mon, 19 Aug 2019 07:56:30 GMT https://community.cloudera.com/t5/Archives-of-Support-Questions/YARN-used-2000-of-memory/m-p/144438#M19752 jade_liu 2019-08-19T07:56:30Z https://community.cloudera.com/t5/Archives-of-Support-Questions/YARN-used-2000-of-memory/m-p/144439#M19753 <P><A rel="user" href="https://community.cloudera.com/users/2065/jadeliu.html" nodeid="2065">@Jade Liu</A></P><P>You should look into the option to upgrade your system.</P><P>HDP and Ambari needs to be upgraded.</P><P>You can increase yarn memory.
