마스터 노드에서 : 포트 8040에 바인딩 java.net.BindException

Question

마스터 머신에서 (클러치로) 마스터/etc/hadoop/salve를 사용하는 2 노드 클러스터 (hadoop 2.6.0)가 있습니다.

start-yarn.sh 

JPS를 호출 한 후

:~$ jps 
11821 SecondaryNameNode 
11114 NameNode 
12037 ResourceManager 
11432 DataNode 
12674 Jps 
12363 NodeManager 

을 보여줍니다 분 이내에 NodeManager는 않고 BindException으로 사라 : 주소를 이미 로그 파일 (아래 붙여 넣기)에서 사용. 포트 8040은 열리고 ResoureManager에 의해 사용됩니다. 마스터
