Hi Zhenyu,
Sorry for the delay. I started working on this a while back, before I
left my job for another company. Since then I haven't had much time to
work on HBase unfortunately :(. I'll try to dig up what I had and see
what shape it's in and update you.
Cheers,

Sorry boys, but I won't be able to make the HUG tonight. I have a
doctor's appointment with conflicting times that can't be moved. I'll
see you all at the hackathon tomorrow though :).

Hi Saptarshi,
HBase should recover from WARNs like that. We'd need to see more information
around that to get full context.
Can you run your command again with DEBUG enabled and provide a full log?

Hi Fernando,
It is recommended that you run ZooKeeper separate from the Region Servers.
On the memory side, our use of ZooKeeper in terms of data stored is minimal
currently. However you definitely don't want it to swap and you want to be
able to handle a large number of connections. A safe value
Hi Bryan,
FYI, I think the latest trunk (with HBASE-1639), should fix the problems you
were seeing.
Thanks,

Hi Bryan,
For the latest trunk, are you using your own zoo.cfg, or overwriting the
options from hbase-default.xml?

Hi Fleming,
That warning is harmless. It should recover after such things. If you ever
see some fatal problems (crashes, data loss, corruption, etc) after such a
thing let us know.
HBase should handle multiple clients writing to the same table fine. You
will get better performance if they are wri
igned to other

Hi Murali,
Sorry I'm late the join the conversation. Yes, running a full ZK
quorum (3 or 5 servers) is key for handling the sort of load you are
seeing.
About the RegionServer not coming back up, can you provide us the full
logs (with DEBUG enabled) on those machines?
Thanks,

Also in the shell, try the zk and/or zk_dump commands. I'm curious
what, if any, errors those give you.

Do you see a line with "Quorum servers: ..."? That is where ZooKeeper
is expected to be running. Can you reach those host/ports?
Can you try the ZooKeeper admin commands?

Hi Alexandre,
I'd recommend you contact Cloudera directly (i...@cloudera.com or
train...@cloudera.com). Also you can try the Hadoop list (
core-u...@hadoop.apache.org). This type of questions belongs better with
them.
Cheers,

I like this a lot Guilherme. Perhaps we should open a JIRA with them so we
can track these great ideas.

This is better directed at the Hadoop mailing lists. I've added hadoop core
user mailing list to your query.

Take a look at architecture page on the wiki:

Hi Bradford,
What's your conf/zoo.cfg look like? Is your ZooKeeper up? Can you connect to
it from the RegionServer machine?
