No demarcation but in KeyValue, we keep row, column family name, column
family qualifier, etc.,
What you seeing Varun (or think you are seeing)?

Hi,
I was looking at PrefixFilter but going by the implementation - it looks we
scan every row until we hit the prefix instead of seeking to the row with
the required prefix.
I was wondering if there are more

Hello Aman,
Thank you so much for the quick response. But why would that happen? I
mean the required env variables are present in hbase-env.sh already. What
is the need to source bashrc?
Consider a scenario
Every quarter the HBase PMC has to make a report to the Apache Board. Here
is what we sent for this period (a minor, private item has been redacted).

HBase is a distributed column-oriented database
built on top of Hadoop Common and Hadoop HDFS
ISSUES FOR THE BOARD’s ATTENTION
Turn it on by default in trunk/0.95 I'd say.

Hi Nitin,
You got my question correctly.
However, I'm wondering how it's working when it's done into HBase.
We use the default MapReduce partitioner:

Hi Greame,
No. The reducer will simply write on the table the same way you are doing a
regular Put. If a split is required because of the size, then the region
will be split, but at the end, there will not

hi,
There are some physical machines which each one contains a large ssd(2T)
and general disk(4T),
and we want to build our hdfs and hbase environment.
What kind of workload do you intend to run on these machines?
Make a patch for the reference guide that points to this Otis? Or just
tell me where to insert?
Thanks,

With regard to number of column families, 3 is the recommended maximum.
How did you come up w/ the number '3'? Is it a 'hard' 3? Or does it
depend? If the latter, on what does it depend?
Thanks,

Try setting the hbase.balancer.period to a very high number in you

From http://hbase.apache.org/book.html#number.of.cfs :
HBase currently does not do well with anything above two or three column
families so keep the number of column families in your schema low.
We should add more to that
for initial experiments (For example, see
https://repository.apache.org/content/groups/snapshots/org/apache/hbase/hbase-client/0.95.0-hadoop2-SNAPSHOT/).
Let us know if you'd like us to package things otherwise.

From my experiments (with 0.92 CDH4.1.2), the max versions is applied in a
