Hi Jean
Before replying as to what i know, region splits can be configured too.
Ok, now on how the split happens
- You can explicity ask the region to get splitted on a specific row key.
If you know that splitting on that rowkey will yield you almost equal
region sizes.
- Now when HBase tries
the default behaviour and split
based on the row number instead of the midkey, can I hook somewhere?
Or will I have to disable the default split (by setting the
maxfilesize to something like 20GB) and run a job to split the regions
manually?

As note of caution just don have two empty qualifiers in the same CF but u
can still have empty qualifiers in diff CFs.

Just fine.. Go ahead.. :)
Can you do one thing.
When you stop the services do this way
- Stop the RS
- Then stop the master.
That is always better i feel.

HBase shipping a generic framework for different interfaces is needed for
ease of use for the users. +1 on the idea.
Getting out the correct result for float values, positive and negative

This will help to solve that problem
The way that Anoop has suggested will make you issue a scan command from
the client but the CP hook will tel you what are the KVs in the memstore
based on that particular scan's current read point.
I think to scan the HFiles directly are you using MapReduce? Or you are
directly reading the
I remember there was another user too who got the same issue. He thought
the minor compaction to be major compaction and was saying that the setting
that we provide to disable the majorcompaction was not working/not taking
effect.

My question is this. If a compaction fails due to a regionserver loss
mid-compaction, does the regionserver that picks up the region continue
where the first left off? Or does it have to start from scratch?
- The answer to this is, it works from the beginning again.

Hi Pankaj
Is it possible for you to profile the RS when this happens? Either may be
like the Thrift adds an overhead or it should be some where the code is
spending more time.
As you said there may be a slight decrease in performance of the put
because now more values has to go in but should
Wha is the rate at which you are flushing? Frequent flushes will cause more
files and compaction may happen frequently but with lesser time.
If the flush size is increased to a bigger value then you will end up more
time in the compaction because the entire file has to be read and rewritten.
Interesting. Need to check this.
May be we should configure different names for the local output directory
for each job. By any chance both jobs are writing to the same path?

Could you give us some more insights on this?
So you mean when you set the row key as 'azzzaaa', though this row does not
exist, the scanner returns some other row? Or it is giving you a row that
does not exist?
Or you mean it is doing a full table scan?
Which version of HBase and what type of
Same question, same time :)

HLogs are for recovery.
HLogs are mainly archived by HBase. And the current live HLogs are
periodically rolled.
hbase.regionserver.logroll.period
hbase.master.logcleaner.ttl
hbase.master.logcleaner.plugins
