Subject Re: Hbase on 64-bit Windows 7: "hostname not provided"
Date Tue, 19 Jan 2010 00:51:57 GMT
Hi stack

Environment is cygwin (version 1.7), Windows 7 64-bit

This was the only way I could manage to get hbase up (with a standalone
zookeeper server) , problem does not exist on Unix (Centos) but that is
expected also I am working to have complete installation
hadoop/hbase/zookeeper running on the Mac will be happy to follow up on

As far as adding "workaround", absolutely (I tried just about anything, as
the original author of this issues, I have had no problems running
"self-managed" zookeeper on Windows 32-bit XP

(fyi, I did not try to "force" IPv4 , but I did try change cygwin sshd and
ssh configuration files to use IPV4, no effect),

btw, thanks for your great work, product (hadoop family) is phenomenal!


Following are sequenced steps and configuration files used (IndexedRegion
server parameters is of course optional)

Sequence of run:

1.start zookeeper (zkServer.sh start)  (ping to check "live" status:
zkCli.sh -server

2. start hadoop

3. start hbase

        <description>The directory shared by region servers.
        <description>The mode the cluster will be in. Possible values are
      false: standalone and pseudo-distributed setups with managed Zookeeper
      true: fully-distributed with unmanaged Zookeeper Quorum (see




and  zoo.cfg file

# The number of milliseconds of each tick
# The number of ticks that the initial
# synchronization phase can take
# The number of ticks that can pass between
# sending a request and getting an acknowledgement
# the directory where the snapshot is stored.
# the port at which the clients will connect
