Hello Anoop,
Thank you for your answer. The QualifierFilter on T specifies a minimum
value not one that has to be matched exactly, so merely adding a specific
qualifier value directly to the scan does not work if I understand
correctly :-/

Hi,
Thank you very much for the clarification! The JIRA task is especially useful
so that I can follow the status of this bug/feature.
According to what you say and what I read in the docs, when I do a major
compact after the deletes it should resolve the problem - but it doesn't :(
Even if I
Hi Cristofer,
No problem... I am happy to share and learn.. :)
Regarding timestamp based column family, I haven't thought about it. But my
only concern is no of column families. I read somewhere that HBase is not
good at handling more than 100 column families.

Heh. Usually it is not good to have more than two or three, actually.
See [1], and may be also [2].

serial number can be first part of rowkey and model number can be second

Hi,
I'm using endpoint coprocessors to do intense scans in parallel on some
tables. I log the time it takes for each coprocessor to finish its job on
the region. Each coprocessor rarely takes longer than a few seconds,
maximum of 5 seconds (there are only 5 regions on the tables right now). As

Hello list,
I have raised a JIRA(HBASE-6430) for a small modification in
Hbase book. Please have a look at it and let me know if I have not
done it properly. Pardon me if things are not put in the appropriate
way, as it is my first attempt. Many thanks.

Kevin:
Can you pastebin the log snippet from region server just before it died ?
How frequent were your coprocessorExec() calls ?
What HBase version were you using ?
Thanks

The log snippet just before the regionservers die look like this:
2012-07-19 09:49:18,551 INFO project.coproc.IndexEndpoint: putting new
rowkey
2012-07-19 09:49:18,551 INFO project.coproc.IndexEndpoint: new rowkey put
2012-07-19 09:49:18,551 INFO project.coproc.IndexEndpoint: coproc time:
1227 ms
Can you paste more of the region server log after 09:49:18,551 (till the
region server died) ?
Thanks

That's it. That's the end of the regionserver log. In the master's web UI
the regionserver is in the table labeled "Dead Region Servers."
In the master's log there is:
2012-07-19 07:02:04,016 INFO
org.apache.hadoop.hbase.zookeeper.RegionServerTracker: RegionServer
ephemeral node deleted, processin
We are using 0.94 and 1.0.3 too
Best wishes

Yes I was having this doubt. So if you know exactly the qualifier names in
advance you can use this scan way.
Else filter only u can use.
QualifierFilter just checks the qualifier name only which CF it is part of is
not checked.
So the similar qualifier names in both T and S will get filtered ou

Yes I was having this doubt abt ur use case. I assumed ur use case is like u
know the qualifier names in advance. :)

Working on it.
The only piece left now is to stabilize the tests a bit to get more confidence
in the build.
I sunk RC0 yesterday, because of test instability. I will probably tag RC1 over
the weekend (or possibly tomorrow).
