I have three question:
1 How large a region will be, if i want to use map-reduce to analyze the
data in hbase table.
2 How many region in a region server is suitable?
3 If the rowkey in my application is not dispersive such as md5 or hash,
how can i control the hotspot of region split?
thx

Hi,
Pardon me for asking such a stupid question.
I recently read an article about HBase basic architecture here:

What really makes me wonder is, what if HBase is installed on machines
where there is no HDFS?
For example, ther

Hey Guys,
We are seeing an issue where Master dies with something like the following.

Concurrent GC (a.k.a CMS) does not mean that there is no more pause. The
pauses are reduced to minimum but can still happen especially if the
concurrent thread will not finish their work under high pressure. The G1
collector in JDK 7.0 pretends to be a better collector than CMS, but i

in a Hbase shell -- adjusting block-size and region-size ? or should I
store them in HDFS and store the pointer in Hbase?
http://wiki.apache.org/hadoop/Hbase/FAQ_Design#A3
says not to go beyond 10MB per cell.

I don't think so.

Hi Ted:
