How can I write text in HDFS using CMD

0 votes

Does Hadoop provide any option to write text into a file stored in HDFS using CMD? Can we use linux command to do so?

I tried this command:

hadoop fs -appendToFile "abc"  /abc/abc.txt

But this command does not work.

Hadoop put & appendToFile only reads standard input.

hdfs dfs -appendToFile file /hadoop/hdfs_file

hdfs dfs -appendToFile file1 local_file2 /hadoop/hdfs_file

Refer to this document:

https://hadoop.apache.org/docs/r2.4.1/hadoop-project-dist/hadoop-common/FileSystemShell.html#appendToFile
