我在 ubuntu 13.10 上使用 hadoop 1.2.1。 我正在运行输入文件大小为 25GB 的排序问题。但是我收到错误:

排序示例对 10GB 的输入文件工作得很好。 我试图增加 JVM_ARGS 和 MaxPermSize。但问题仍然存在。 任何建议将不胜感激。
最佳答案
此问题可能有多种原因，您需要检查是否达到作业数量限制？ 1) 日志目录空间不足，无法创建日志，
permissions issue. 2) ulimit threshold that causes insuffucient allocation of memory. 3) OOM on the child or unable to allocate the configured memory while spawning the child 4) Bug in the child args configuration in the mapred-site 5) Unable to write the temp outputs (due to space or permission issue) Hope it will help you
