use hdfs as normal file system?

[Pierre Antoine DuBoDeNa <pa...@gmail.com>]

Hello,

I have installed hdfs to use it with hadoop and hbase. I am wondering if i
can use it as a normal file system too that just connects several HDDs ?

For example i can see the files i have stored through the webinterface
(browse filesystem) or with the dfs commands. However if I go to the exact
location in the hdfs directory there is nothing. Everything is stored in an
"hdfs format".

Is it possible to go to /app/hadoop/tmp/data/text.txt for example in some
way? Can i use it in such way?

I just want to avoid to install NFS servers as i already have in place
hdfs.

Best,
PA

Thanks for your reply!! This is the only think i found related on the web..
but i don't see much "support" let's say for it.. so i am not sure if it's
the best choice..

What kind of issues you get in your company? (What company? if i may ask..
I mean I deal with scientific documents mostly.. the files most of the time
will be "static" we just have to read them several times to apply
algorithms").

Hi Pierre,

According to my knowledge HDFS is not compliant as a normal
filesystem. But you can use Fuse as a workaround to mount it. This is
what we do in our company, but we were experiencing some stability
issues.
