Question

当我启动 NodeManager 时，我在日志中看到了这个错误。此作业总是在服务器启动时启动，如何删除此作业并解决问题？

Application application_1511362704902_0007 failed 2 times due to AM Container for appattempt_1511362704902_0007_000002 exited with  exitCode: -1000

Answer 1

我做什么:停止所有 yarn 服务

hdfs dfs -rm -r -f /home/?p.ermakov?
hdfs dfs -rm -r -f /spark-history/*
hdfs dfs -rm -r -f /spark2-history/*
rm -rf /hadoop/yarn/local/usercache/
rm -rf /hadoop/yarn/local/filecache/

并启动所有 yarn 服务。这为我解决了问题。
