Thank you for the link Anil it was a good explanation indeed.
It's not recommended to do put/deletes across
region servers like this.
That was not my intention, I want to keep the region for the aggregates
Hi,
I am running Hive and HBase on Amazon EC2. By following the tutorial:
https://cwiki.apache.org/confluence/display/Hive/HBaseIntegration , I
managed to create a HBase table from Hive and insert data into it.
It works but with a low performance. To be specific, inserting 1.3 Gb

Hi,
I have a use case in which I need to store segments of mp3 files in hbase.
A song may come to the application in different ovelapping segments. For
example, a 5 min song can have the following segments 0-1,0.5-2,2-4,3-5. As
seen, some of the data is duplicate (3-4 is present in the last 2
Hao,
A couple thoughts here.
This could be related to many things.
1. Did you pre-split your regions? If not, you could be hot-spotting on a
single server and then waiting for the region to split. If that is the
case, you could actually only be using a single server for much of your
load (if not
bq. Will hbase do some sort of deduplication?
I don't think so.
What is the granularity of segment overlap ? In the above example, it seems
to be 0.5
Cheers

Matt,
Thank you for the lightning reply.
I will try out what you have mentioned in these days, thus I could tell
you some news on the issue in detail.
Thank you again. Your suggestions show me the way. =)

hi, guys,
I am using hbase 0.94.9. And setup replication from a 4-nodes master(3
regserver) to a 3-nodes slave(2 regserver).
I can tell that all source regservers can successfully replicate data.
However, it seems for each particular table, only one regserver will handle
its replication at each
Region servers replicate data written to them, so look at how your regions
are distributed.

Hey all,
I try to use multi get for receiving different versions of row but it give
me only one always. For example I have table log, and column family
data:get. I put a lot of versions of row/data:log. Now I try to get all
versions of this key.
As it said in manual
J-D, thanks for the tip.

Hi,
I am new to hbase and am trying to achieve the following.
I am reading data from hdfs in mapper and parsing it..
So, in reducer I want my output to write to hbase instead of hdfs
But here is the thing.

You can use HBase's MultiTableOutputFormat:
http://hbase.apache.org/apidocs/org/apache/hadoop/hbase/mapreduce/MultiTableOutputFormat.html
An example can be found in this blog post:

I think my app wants to hit a particular region all the time. Since my table is
only read-only (lookup). I have created more than one and randomly pick one to
use. This way I can load the whole cluster. Is there a feature in Hbase which
lets coprocessors run on another region server on

Or if you'd like to be able to use SQL directly on it, take a look at

Hi ,
Can you please query for the schema of the table and show us here.
Would like to know what is value for VERSIONS that you have set for the
column family . I hope you have set it to 10.
Ex:http://myhost.com:8080/log/schemahttp://myhost.com:8080/log/data:get/0,1377633354/?v=10

sqoop can not support export hbase data into mysql
