Hi Qian,
I am not sure if it will work. You should be able to back port it such a
way so that it works with gcc 3.*/4.*, but again I have never tried it.

Thanks Mahadev, I follow the installation instruction in the README,
autoreconf -i -f
./configure --prefix=$dir
make
make install
until "./configure --prefix=$dir", there is no error, however, errors came
when I did make,
My plan is change the compiler from gcc to g++, and solve the compile err

There is no full stop for our system. It (had better) will run forever.
That said, we have no permanent information in ZK that is not persisted in,
say, SVN.

Sounds like a nice test, and it's great to hear that ZooKeeper works well there.

Note that most of these seem to be related to client issues, especially GC.
If you configure in such a way as to g
No. This should not cause data loss.
As soon as ZK cannot replicate changes to a majority of machines, it refuses
to take any more changes. This is old ground and is required for
correctness in the face of network partition. It is conceivable (barely)

Ted thanks for the info.
I've created a wiki page
http://wiki.apache.org/hadoop/ZooKeeper/ZooKeeperOnEC2
to capture details of running ZK on EC2. If you or anyone else would
like to update it with information please do so.

I disagree with the original post that this is a problem, even in EC2.
Having the persistent copy on disk is exactly what makes the rolling restart
work so well.
I think that the misunderstanding is that this on-disk image is critical to
cluster function. It is not critical because it is replicat
We have used EC2 quite a bit for ZK.
The basic lessons that I have learned include:
a) EC2's biggest advantage after scaling and elasticity was conformity of
configuration. Since you are bringing machines up and down all the time,
they begin to act more like programs and you wind up with boot sc

Hi Qian,
What issues do you face? I have never tried compiling with the
configuration below, but I could give it a try in my free time to see if I
can get it to compile.

Hello
I wanna set up a zookeeper ensemble on amazon's ec2 service. In my
system, zookeeper is used to run a locking service and to generate
unique id's. Currently, for testing purposes, I am only running one
instance. Now, I need to set up an ensemble to protect my system
against crashes.
Hi all:
I'm writing to ask you to do me a favor. It's urgent. For some unchangeable
reason, I have to compile "libzookeeper_st.a", "libzookeeper_mt.a" on an old
system:
gcc 2.96
autoconf 2.13
automake 1.4-p5
libtool 1.4.2
I cannot not compile the target lib in the usual way, and this task drives
