Hi,
My standalone HBase instance, installed as per the 'getting started' section
at http://hbase.apache.org/book/quickstart.html, doesn't work insofar.
I get in the log file:
2012-11-23 18:26:37,827 INFO org.apache.zookeeper.ClientCnxn: Session
establishment complete on server localhost/127.0.0
Thanks! seems to be working!

View this message in context:

Maybe this should be added in the documentation as an hint?

As for myself, I'm not 100% sure why it is necessary to change this IP
address from one loopback address to the other, so I cannot fully suggest a
change in that respect myself.. anyway, it may seem that change is only
necessary in Ubuntu/Debian, if that matters in terms of how many people
need to
Dear all,
I wanted to ask a question..
Do Hbase Aggregate Functions such as rowcount, getMax, get Average use
MapReduce to execute those functions?
Thanks :D
Regards, Dalia.
You have to use MapReduce for that.
In the HBase in Practice´s book, there are lot of great examples for this.

It's included here http://hbase.apache.org/book.html actually, maybe link
the 'getting started' page to that page, unless it's becoming unfavorably
cyclic.

Hi, but you do not need to us M/R. You could also use coprocessors.
See this site:
https://blogs.apache.org/hbase/entry/coprocessor_introduction
-> in the section "Endpoints"
An aggregation coprocessor ships with hbase that should match your
requirements.
You just need to load it and eventuall
Do you think it would be a good idea to temper the use of CoProcessors?
This kind of reminds me of when people first started using stored procedures...

It 's weird that hbase aggregate functions don't use MapReduce, this means that
the performance will be very poor.
Is it a must to use coprocessors?
Is there a much easier way to improve the functions' performance ?

We have a section on loopback here:
http://hbase.apache.org/book.html#basic.prerequisites
What should we add to it?

I did as you suggested by listing java, loopback and ssh as prereqs
for getting started
Actually coprocessor can be used to implement MR-like function, while not
using Hadoop framework.

Hi, I have figured out the problem... The XML snippet in previous email works
for HBase 092 but not for 094. By consulting HBase-default.xml, it can be done
to disable all compact ions. Thanks all the same.
