Hello,
we are in process running our first load test on a Cloudera test cluster
with 8 region servers. We also have Ganglia in use for monitoring. I
wonder what counters one should watch out during the tests to identify
possible bottlenecks, improvements etc ... Is there some kind of quick

Hi All,
I have a problem in HBase fully distributed mode with four node cluster.
My Hadoop and zookeeper are working properly. The HBase also starting and
running properly but it is not stopped when I give the stop-hbase.sh command.
Thanks in advance.!
Regards,
You need to copy both the Hadoop and HBase JAR to both YCSB/lib/ and
YCSB/hbase/lib/.
BTW - I never got a chance to respond, but thanks to those who
responded to my inquiry last week. Turning on RPC debugging showed me
that the issue was as simple as a problem with the box running YCSB as

Hi,
I have confronted with the same situation. My solution is to stop
regionservers, then master, then zookeeper manually.

Hi Jean,
The Problem is continued even the Active master is properly killed.
How can we make the Active master and backup master use the same zookeeper
ensemble.

Look at the .log and .out files, something might just be blocking you.

In debugging another issue, I noticed that IPC Reader threads kicked off in

as it is now, they could prevent the program from exiting if for some reason
the thread pool isn't shutdown after main exits.

It's safe, all the big installs I know are either on some heavily
patched 0.89 or a late version of 0.90.
You might want to do an export before upgrading, or a complete HDFS
distcp, just for good measure.
Also read this guide from the online book:

This used to be leftovers from old bugs we had with the old master,
but I'm not aware of any current bug that cause that. Maybe a failed
split that rolled back, only your master and region server logs can
tell.
Looking at the output it seems that your table is healthy, but that

Hi Thomas,
No specific guide for monitoring performance but I strongly recommend
that you read the following sections of the book:

verify that
Hi Jacques,
Sorry to hear about that.
Regarding MapR, I personally don't have hands-on experience so it's a
little bit hard for me to help you. You might want to ping them and
ask their opinion (and I know they are watching, Ted? Srivas?)
What I can do is telling you if things look normal from
Yes - this was also the reason in the thread I had linked earlier.
The reason is that there are two versions of the Reducer. One in the
mapred package (that uses Iterator) and the new one in mapreduce
package (that uses Iterable). It is likely that you used the new one
with the old reduce
