Hi Marco,
Did you make sure that hbase-site.xml is present the classpath of your java
app? As per your error, it looks like thats not the case.
Thanks,
Anil

It should be possible to build an application that's using both client
library versions using something like JarJar [0] to munge class names. I

1500 reads/sec to meta with no client activity sounds high, but... how big
is the cluster (how many region servers) and how many thrift gateway
processes are you running? Are you running any other gateways as well (REST
or Thrift2)?

However, the application needs to compiled with 0.98 jars because the RPC
has changed.

I tried it also completely without setting the config manually,
so just
val conf = HBaseConfiguration.create()
directly on the server, where hbase/hadoop etc. is installed. Same

I disagree. Before adding something like that to the ref guide, we should
actually agree to support it as a migration strategy. We're not there yet.
And although it's a heroic process, we can take steps to make it less
kludgy if so.

Hi,
Hbase is installed correctly and working (hbase shell works fine).
But I'm not able to use the Java API to connect to an existing Hbase Table:

val conf = HBaseConfiguration.create()
conf.clear()
conf.set("hbase.zookeeper.quorum", "ip:2181");
conf.set("hbase.zookeeper.property.clientPor

I am designing an architecture for a website to show analytics on a huge

are contiguous will be read at once (say a few thousand rows) and some d
