JD hi
The system is under heavy load only via hbase (no map reduce running).
Another thing is that we have hard constraints in latencies, therefore if
this point on performance problem i would like to fix it. The GC seems
fine too.
I see around 300 message like this in 10 hours of run, approx
Richard,
Let's see if I understand what you want to do...
You have some data and you want to store it in some table A.
Some of the records/rows in this table have a limited life span of 3 days,
others have a limited life span of 3 months. But both are the same records? By
this I mean that both

Thank you!
Have you seen this from the API javadoc:
Hi,
We are trying to use the aggregation functionality in HBase 0.92 and we have
managed to get the test code working using the following command:
java -classpath junit-4.10.jar:build/*:$HBASELIBS/* org.junit.runner.JUnitCore
org.apache.hadoop.hbase.coprocessor.TestAggregateProtocol
Closer
Have you loaded AggregateImplementation into your table ?
Can you show us the contents of the following command in hbase shell:
describe 'your-table'
BTW are you using the tip of 0.92 ?
HBASE-4946 would be of help for dynamically loaded coprocessors which you
might use in the future.
Cheers

Hi,
I am trying to do bulkload into a HBase Table with one column family,
using a custom mapper to create the PUTs according to my needs. (Machine
setup at the end of the mail)
Unfortunately, with our data it is a bit hard to presplit the tables
since the keys are not predictable thaat good
If you move the region to another host, do you same same perf (Perhaps
some hardware issue?).
Done more testing today. Is not related to a particular region, it
happened today with an other region on same machine. Also is not a
permanent issue, after some time I retried and the scan was fast
Just an update on this thread:
JD told me via IRC that this problem happens because my HBase manages
Zookeeper and when I restart HBase, Zookeeper is restarted along with it
and the Zookeeper client has a bug that doesn't allow it to work after a
Zookeeper restart.
He suggested a workaround
Culvert was originally introduced at Hadoop Summit 2011, but recent updates
have made it very applicable to current systems. Recently, we added support
for Accumulo as well as upgraded HBase support to 0.92. Since Hadoop
Summit, there have also been significant code cleanup and added some small
We have a 6 node 0.90.3-cdh3u1 cluster. We have 8092 regions. I
realize we have too many regions and too few nodes…we're addressing
that. We currently have an issue where we seem to have lost region
data. When data is requested for a couple of our regions, we get
errors like the following on

Thanks for the update, Jesse.
Let us know of any feature Culvert needs from HBase.
After cloning Culvert, I got:

Wow, that's embarrassing - project not building...
It's because accumulo's release is no longer deployed into the standard
apache maven repository. Maybe one of the accumulo committers can shed some
light on where to find it?
I'll make some changes and have it at least compiling from the raw
Thanks for the hint. That works.
I had to modify culvert-accumulo/pom.xml so that it looks for

Indeed that the simplest approach is usually best.
The simplest way to manage automatic expiration of data over various lifetimes,

Tarball looks good to me.
Took it a spin local mode, created some tables, inserted some data, scanned
data, removed tables, etc.

Hi Alex,
see http://hbase.apache.org/book.html#hadoop
Make sure you replace the hadoop.jar in the 0.90.4 directory with the
hadoop.jar from the HDFS distro you pick. Otherwise you will get
incompatiblity exceptions about connecting to the file system.
