Hbase on 64-bit Windows 7: "hostname not provided"
Has anyone successfully run hbase on 64-bit Windows 7? I was able to get hbase working on Windows XP following these instructions:
http://highestpoint.biz/2009/10/installing-hbase-on-windows/
I followed the exact same instructions for a PC running 64-bit Windows 7 but when I run start-hbase.sh I get this error:
": hostname nor servname provided, or not known"
On my Windows XP PC I get prompted twice for the password but on my Windows 7 PC I only get prompted once and after that I get errors trying to run commands in hbase shell.
Does anyone know why I get the error about hostname not provided?
Thanks.
John

I wish I knew - it worked for me on Windows XP. I tried following Dave's suggestion and disabled ipv6 on my lan network and also added the following registry value (DWORD type) set to 0xff to completeley disable ipv6:
KEY_LOCAL_MACHINE\SYSTEM\ CurrentControlSet\Services\ Tcpip6\Parameters\ DisabledComponents
I rebooted my machine but still got the error when I tried to start up hbase. In my hbase-default.xml file my hbase.zookeeper.quorum parameter is set to 127.0.0.1. This config worked for me on my Windows XP machine. I noticed my conf/regionserver file has the value "localhost" so perhaps that is where zookeeper is getting the value localhost but as per Dave's email is adding a newline to it. I tried adding an entry for "localhost\n" in my ~/.ssh/known_hosts file but that did not work either.
I'm open to suggestions at this point.

I have a patch that runs zookeeper within the master JVM, but I dont
think it would entirely solve this for you, because clients use
'localhost' the value we ship with in hbase-default.xml to locate the
ZK process. You'd just shift the problem a bit.
How can we make life easier for you cygwin users? Why is there no
localhost for you?

I've seen a similar message in cygwin after upgrading to hbase 0.20. I
believe that start-hbase.sh uses ZKServerTool to get the zookeeper hosts
from the conf file. However, on windows or cygwin, it returns hosts with a
newline as part of the name. As a result, start-hbase tries to ssh to
"hostname\n" or so, and windows fails. I have a colleague who tried it on
Windows 7 (64-bit) and I think it worked after he disabled IPv6. Perhaps
with IPv6, windows is stricter about the name and can't handle the white
space. Even with Windows XP, though, since hbase 0.20 I've had to keep a
known_hosts file with an entry containing a newline to match what
start-hbase gets from ZKServerTool.
