As an aside, if there are changes we'd like to see in YCSB upstream has
started taking patches again with a bit of prodding.

Also, if you do end up using dynamic loading, you'll need a way to version
your filters because the RS will not reload a JAR if it changes.

I haven't tried dynamic loading of filters on RS, but I know it does exist.
See https://issues.apache.org/jira/browse/HBASE-9301.
If you still can't get it to work, then I suggest distributing your filters
to the RS and restart them. Let us know how everything works out.

Hi,
I've read that on a modern hardware I should increase the value of
io.file.buffer.size parameter of HDFS, up to 128kb or so. [1] Does this
advice still hold true in the context of HBase? We've done a series of
performance benchmarks with the different values of it, but couldn't
observe a notic
Thanks Kevin!
I was under impression, probably mistakingly, that as of 0.96 placing
the filter on hdfs under hbase lib directory is sufficient and RS should
load the filter dynamically from hdfs. Is that not the case?

Did you restart HMaster? You can check the master's runtime conf at
/conf and that should show this config.

BTW, the error looks like you didn't distribute your custom filter to your
region servers.

Do you use ipv6 ?
If so, this is related:

Matt,
You should create your own proto file and compile that with the Google
Protocol Buffer compiler. Take a look at the SingleColumnValueFilter's
code:

Hi,
I have connected a client machine with two network interfaces to an
internal, isolated HBase cluster and an external network. The HBase cluster
is on its own private LAN, away from the external network. After installing
and updating the Hadoop and HBase configuration files on the client

Please confirm that the issue you observe was with Delete#deleteColumn
(different from the method mentioned in subject).
Can you tried with 0.94.24 (the latest 0.94 release) ?
If you can capture this using a unit test, that
Thanks All.I will get back if I take that direction.

snapshots are off by default in 0.94 because it is a new feature backported
from the 0.96 branch.
from 0.96 snapshots are on by default.

Thanks Jean,
If i put the same value in my table for a particular column for a rowkey i
want HBase reject this value and retain old value with old time stamp.
In other words update only when value changes.

Hi Krishna,
HBase will store them in the same row, same cell but you will have 2
versions. If you want to keep just one, setup the version=1 on the table
side and only one will be stored. Is that what yo mean?

Hi,
I have a HBase table which is populated from pig using PigStorage.
While inserting, suppose for rowkey i have a duplicate value.
Is there a way to prevent an update?.
I want to maintain the version history for my values which are unique.
Regards,
Krishna
Do you want some sql-on-hadoop could access hbase file directly?
I did a quick search and find
http://www.slideshare.net/Stratio/integrating-sparkandcassandra(P35), but
not sure if I understand correctly.
