getting files in hdfs
Good Day,
I successfully installed and copy a test file to HDFS. I was wondering if is
it possible to directly access the file without getting it out first from
the HDFS.
Regards,
Garri

Thanks Ted for the clarification. That's a great approach.

That isn't (I don't think) what I was referring to.
I meant http://namenode:port/data/path-name
This gives you the entire file at a time.

Thanks Thomas and Ted,
when I use:
${PATH_TO_HADOOP_INSTALL}/bin/hadoop dfs -ls
it list:
/user/hadoop/sample.txt
I was wondering if how can I access that file from let's say a web interface
to direct on that file.
<!-- Like it was just mounted -->
<a href="/user/hadoop/sample.txt">Sample Text</a>
AFAIK the given example above will not work he he he
In order for me to access the file I have to -get sample.txt
/path/to/webroot/ the file and put it to my webroot and creating a the link
that will point to the file retrieve. I was thinking of other ways or
possibilities to bypass that process.
@Ted
yeah I explored that Browse file system and I think I can use that.
Is it possible to mount the /user/hadoop?
Thank you very much,
Garri

You can also get to the file via HTTP.

What do you mean by 'directly access the file'? HDFS provides several
file operations. Type '${PATH_TO_HADOOP_INSTALL}/bin/hadoop fs' to see
an appropriate usage message.
