Hi,
I wrote a RegionObserver which does preCompact.
I activated in pre-production, and then entire cluster dropped dead: One
RegionServer after another crashed on OutOfMemoryException: Heap Space.
My preCompact method generates a KeyValue per each set of Column Qualifiers it
sees.

Hi,
Was the possibility of compressing RPC data sent from HBase client to Region
server?
Some data pattern could benefit from this tremendously.
Another thing - As a work-around, can be this be done by using a special
coprocessor which will receive the List, decompress it and then call

Hi,
Can the following scenario occur?
Create a Put for (rk1, cf1, cq1, value=1L)

Inside implementation:

Flush kicks in
Client attempts a retry and succeeds, thus same put is written for the s
Hi,
If I deploy a Region Observer to a table using HDFS Jar, is it possible to
deploy a new version, enable/disable the table to get that new jar hot
deployed, without restarting all the region servers?

Hi,
We ran the QA test again, this time with INFO message on at the client side
(HTable).
We saw many retry attempts which failed on RPC timeouts (we use the default of
60 seconds).
I guess when this error occurs, the increment shouldn't really happen, right?
This may explain the diff we see f
Hi,
I wrote a RegionObserver.
I'm collecting very important metrics in that observer and I would like to
expose them in the JMX Server HBase is using.
Is there a way to do that?
Thanks,

Hi,
Recently after upgrading to 0.94.3, my unit test which is using HBase mini
cluster keeps throwing this warning.
Why does it want to delete a table folder?
Can someone elaborate on this exception?
My test it self is setting up two tables, in which only one is used. The one in
the errors is
130 GB raw data will take in HBase since it adds the family name, qualifier and
timestamp to each value, so it can even be 150GB. You can check it exactly, by
loading only one row with one column and see how much it takes on the HDFS file
system (run compaction first).
Next, you 5 times that si
Hi,
I'm looking for a Maven repository that hosts latest HBase version.
I see that central (http://mvnrepository.com/artifact/org.apache.hbase/hbase)
only hosts 0.94.1 and not 0.94.4

I suggest you use a Maven project.
I can copy-paste a small pom.xml for you to get you started.
It will solve all of those missing JARS you have.
Just make sure to install M2Eclipse plugin (Eclipse Marketplace)

One thing I don't get:
If the RS went down, then the RPC connection should have been reset, thus
causing the client to interrupt, right? It shouldn't be a matter of timeout at
all.

Hi,
I've tried using HBaseAdmin.getAlterStatus to check on a HBaseAdmin.modifyTable
command I've issued, but it doesn't work.
Sample Code:
Modifying Table
tableDescriptor = admin.getTableDescriptor(tableNameBytes);
if (tableDescriptor.hasCoprocessor(observerClass

Hi,
I wrote a custom Region Observer.
I'm currently writing an Installer class for it.
In this installer I'm adding the region observer by adding a coprocessor to the
HTableDescriptor, and then calling modifyTable by HBaseAdmin.
My question is: How can I check whether region observer was loaded
I got stuck on missing Maven dependencies.
All our dependencies downloads goes through corporate gateway (Nexus).
I'm not sure it's ok to request to add to follow personal test repo to Nexus:

Hi,

From some reason, any call to the HBase fails. I ran hbck and got the same
