HDFS Command Line Append
问题 Is there any way to append to a file on HDFS from command line like copying file: hadoop fs -copyFromLocal <localsrc> URI 回答1: This feature is implemented in Hadoop 2.3.0 as appendToFile with a syntax like: hdfs dfs -appendToFile localfile /user/hadoop/hadoopfile (it was first suggested in 2009 when the HDFS Append feature was being contemplated: https://issues.apache.org/jira/browse/HADOOP-6239 ) 回答2: cli doesn't support append, but httpfs and fuse both has support for appending files. w301%
