is running 236038656B beyond the 'VIRTUAL' memory limit. Current usage: 52.4 MB of 1 GB physical memory used; 2.3 GB of 2.1 GB virtual memory used.

[2022-03-18 18:26:57.187]Container [pid=92959,containerID=container_1647598528227_0003_01_000002]

輸入下列程式碼時報以上錯誤

hadoop jar wc.jar com.ltj.wordcount.WordCount -Dmapreduce.job.queuename=default /input /output

 

問題原因是container在申請多餘的記憶體時,被resouremanager殺掉了
此處可修改hadoop/etc/mapred-site.xml
新增配置資訊

<property>
  <name>mapreduce.map.memory.mb</name>
  <value>1536</value>
</property>
<property>
  <name>mapreduce.map.java.opts</name>
  <value>-Xmx1024M</value>
</property>
<property>
  <name>mapreduce.reduce.memory.mb</name>
  <value>3072</value>
</property>
<property>
  <name>mapreduce.reduce.java.opts</name>
  <value>-Xmx2560M</value>
</property>

然後重啟hadoop
重新提交任務

找了一天-----555終於解決了
