Hi!
I am new to hadoop as well as cygwin, and as far as I know, you need to
use cygwin in order to use hadoop on win. Unfortunately I'm not allowed
to switch to linux or even use a linux machine to get the dfs running.
Seems there's no other way but the cygwin-way, is there? Anyways, I was
wondering, is there a way to get hadoop daemons running via cygwin, and
then quit the latter? Cause I think I got the namenode and datanode
running (how can I test that, by the way - other than by writing "ps" in
cygwin? Does writing the address and port of the node in a browser and
waiting for the outcome, which is a blank-but-not-error page, tell me
anything about whether the dfs is configured correctly?), yet if I close
cygwin, the daemons shutdown too.
And there's another thing I'd like to ask. I'm writing a Java program
that is supposed to connect to a dfs. As much as I've read the API docs,
I suppose I should use the DistributedFileSystem class, shouldn't I? But
what does creating it's instance actually do? Create me a new filesystem
or rather just a connection to an existing one? What I do is specify a
InetSocketAddress and a Configuration. Can the configuration object be
created using the hadoop-defaul.xml and hadoop-site.xml files?
I know these questions probably sound stupid, but still I'd really
appreciate if someone provided me with some answers. I'm a true beginner
in the matters of hadoop and cygwin, and I'm also quite new to Java,
so please - be gentle ;o)
Regards,
