Nope, it doesn't.
After recompiling, I just changed the $HBASE_HOME to the newly created build
folder. I think that is the only change required?

Does your filter start working if you add it in here w/ a code of its
own and recompile and relaunch?

This change only effects the performance isn't it (particularly for small
cell data), not the actual functionality.

Look in that java file and see how all extant filters are mentioned
and assigned a code. You need to add yours too.

Thank you Angus and Guilherme :). I added the filter jar to $HBase/lib and
the exceptions went away. Although, there now the filter doesn't return any
rows - I have to check this out.

About HBaseObjectWritable, I have used it in serializing(write() method)
and deserializing(readFields()
You have to add it to HBaseObjectWritable too, IIRC. See how other
filters are mentioned in there (The need to do this has to go away. I
filed HBASE-2666).

Even if HBase is running in standalone mode, the scan operation is
still running in another jvm, to be specific, in HMaster process.
So you still have to either put the custom filter jar in $HBASE/lib or
set up the $HBASE/conf/hbase-env.sh properly.

Hi Yoram,
Thanks for your reply. We have structural data and have to search and
sort against each attribute. So, simply IHBase or THBase did not help.
We are studying on some custom implementation that is in between IHBase
and THBase. For that case we may need Coprocessors implemented in HBase.

Hello,
I remember Jon was talking other day that he was trying a single HBase
server with existing HDFS cluster to serve map reduce (MR) results. I
wonder if this went well or not.
A couple of friends in Tokyo are considering HBase to do a similar
thing. They want to serve MR results insi
The problem with your scenario is that if you get partitioned then both sides
will go down because ZK needs a quorum (half plus one). As for Hadoop, by
default it does not support multiple name nodes. The master file lists
secondary name nodes (they just log what happens on the NN). There is
David, we are currently prototyping an Active-Active site scenario so
for now we will be using 2 ZooKeeper servers (one on site a the other on
site b).

The custom filter doesn't need any additional jars.
Another point I forgot to mention is that, I am running this on a single
node (laptop) to test my filter.

Hi all,
I wrote a custom filter and used it with scan. I am getting the
following exceptions. If I use any built-in filters, it works fine. I
searched around and one of the suggestions was to increase the lease
timeout. Since it works fine for built-in filters, I am assuming that this

Just to be clear, you are not actually running exactly 2 ZK nodes are you? I
think one ZK node on your master is sufficient for this size of cluster. If
that node goes down you entire cluster is gone in any case. And remember, you
need to have an odd number of ZK nodes. And 3 nodes probably

Hi,
If you're not going access this logged data as is from HBase and will use it
to produce some statistics, etc. (perhaps via MR jobs), then I wouldn't
recommend using neither date/time nor timestamp as a row key. This will make
HBase write logs into particular RegionServer at one time and thus a

Hi Otis,
Other some basic tests on EC2, I'm afraid not. I was initially
pondering using ElasticSearch as the front end REST and hooking in the
CRUD to HBase underneath, but since HBase is not my primary store (in
