Is it possible to access a hadoop 1 file system (hdfs) via the hadoop
2.2.0 command line tools?
Hello all,
I am trying to access a hadoop 1 installation via the hadoop 2.2.0
command line tools. I am wondering if this is possible at all?
From hadoop 1 I get:
-- snip start --
cs:~$ hadoop fs -ls hdfs://127.0.0.1:9000/
Found 2 items
drwxr-xr-x - cs supergroup 0 2014-02-01 08:18 /tmp
drwxr-xr-x - cs supergroup 0 2014-02-01 08:19 /user
-- snip end --
From hadoop 2.2.0 I get:
-- snip start --
cs:~$ hadoop fs -ls hdfs://127.0.0.1:9000/
ls: Failed on local exception: java.io.EOFException; Host Details :
local host is: "i7/127.0.1.1"; destination host is: "localhost":9000;
-- snip end --
I am trying to find this information via a web-search, but up to now no
success.
Many thanks and best regards!

You can use webhdfs / hftp to access the data from the Hadoop 1 cluster.
