HDFS 命令行追加 [英] HDFS Command Line Append

问题描述

有什么方法可以像复制文件一样从命令行追加到 HDFS 上的文件:

Is there any way to append to a file on HDFS from command line like copying file:

hadoop fs -copyFromLocal <localsrc> URI

推荐答案

此功能在 Hadoop 2.3.0 中实现为 appendToFile 语法如下:

This feature is implemented in Hadoop 2.3.0 as appendToFile with a syntax like:

hdfs dfs -appendToFile localfile /user/hadoop/hadoopfile

(这是在 2009 年考虑 HDFS Append 功能时首次提出的:https://issues.apache.org/jira/browse/HADOOP-6239)

(it was first suggested in 2009 when the HDFS Append feature was being contemplated: https://issues.apache.org/jira/browse/HADOOP-6239 )
