When I use svn plugin within Eclipse to checkout the source code of HBase,
it comes up with "Operation failed" message, which indicates:
svn: Processing REPORT request response failed: Premature end of file.
(/repos/asf/!svn/vcc/default)
svn: REPORT request failed on '/repos/asf/!svn/vcc/default'
If you try svn from command line do you see the same thing? (Its
working for me FYI).

I think not, probably. It is said that the TortoiseSVN or other GUI version,
in my case the plugin in Eclipse, would encounter this problem. And several
weeks ago, there was no trouble during my first time of checking out the
source code.
However, here my trouble is that I could only access the sv
Based on what we saw... there shouldn't be a reason why you don't bump it up to
something north of 32K or even 64K.
Granted our data nodes have 32GB of memory and the fact that we don't have
users on the machine so setting up 64K ulimit -n is really just noise.

I would say "yes", conditionally.
But indeed you have to use add_table.rb to add the copied over regions to the
META region of the target cluster.
And of course if you copy over table data as HFiles you have to at least
disable the table on the source cluster or shut it down before the copy, s

Okay.. so add_table can be run even if there is an existing table by the

You can query Stargate.
E.g.
/usr/bin/curl http://$server:8080/status/cluster
You can see region information in the output.

No and pretty much no.
You cannot simple throw tables together as that would stuff up region
boundaries most likely. I would only replace or add a new table that
way (if at all). And the add_table.rb is more of a kludge as this was
needed to fix sick clusters in the past. This is not something you
Can the data in this table be partitioned ?
If so, you can use hbase TableInputFormat to consume it.

What I'm trying to find is how much improvement in throughput & reduction in
latency can I hope to get by spreading out a table across multiple region
servers.
We have some tables that are wide, but short ... it currently fits in a
single region on a single region server. I'm trying to determine i
FYI You can preconfigure the number of regions when you create your table:

Ted,
I looked at /usr/bin/curl http://$server:8080/status/cluster.
But there is no traffic data there. All the data this interface returns is
already available through HBase web interface.

Right.
Stargate cluster status is centralized view. I use it to monitor the health
of our cluster by selectively querying rows on each region server.

Hi,
I am using hbase shell to verify some konwleges that I have read from
the post of "Understanding HBase and BigTable"
That post says: "If an application asks for a given row at a given timestamp,
HBase will return cell data where the timestamp is less than or equal to
the one provided."
I'd have to look at the shell code, but its probably that the shell is
building the query to be 'give me the KV at TS=19'. The Java API lets
you specify both 'give me exact time' and 'give me time range'.

Hi, ryan, just as you say , now I am using setTimeRange to fulfill my request.
I am just curious on the 'less than' concept,
'If an application asks for a given row at a given timestamp,
HBase will return cell data where the timestamp is less than or
equal to the one provided.'
