AWS EMR 集群在自定义引导时终止

Question

我正在运行以下命令来创建 EMR 集群，并且集群在引导阶段终止

aws emr create-cluster --ami-version 3.1.0 \
--ami-version 3.8.0 \
--service-role EMR.sentmtEMRServiceRole \
--bootstrap-actions Path=s3://ae1-s3-sentmt-anlys/config-nltk.sh,Name="Custom action" \
--log-uri s3://aws-logs-476270297889-us-east-1/elasticmapreduce \
--ec2-attributes InstanceProfile=ec2-sentmt.role,KeyName=ae1-nat-sentmt-anlys \
--instance-groups InstanceGroupType=MASTER,InstanceCount=1,InstanceType=m1.medium InstanceGroupType=CORE,InstanceCount=1,InstanceType=m1.medium

并且日志文件在 S3 存储桶中有以下条目：

  The other application is: yum

这已经很晚了，但对于像我一样遇到这种情况的其他人来说。解决方案可以在这里找到：https://forums.aws.amazon.com/message.jspa?messageID=614195

有两种修复方法。最简单的方法是使用更新的 ami 版本。因此，如果您复制了某人的命令行来启动集群，请将 ami 版本标记替换为：--ami-version 3.9.0

如果您卡在当前的 ami 版本上，您可以通过使用 releasever 修改 yum 命令来解决此问题：

yum --releasever=2014.09 install <package_name>
