Hi,

I created a table in hbase shell with pre split

create 'Test','C',{SPLITS=>['\0x1','\0x2','\0x3','\0x4','\0x5']}

when i put a new value using put command in hbase shell the request is
passed to the different regions.

but, when i put the value in hbase table using java api the request is
passed to the first region.

can any one help me on this, i need to store the value in different region
on basis of the rowkey.

Thx,

Can you please share the code you are using to put those values from
Java so we can take a look?

Here is a sample script to create pre splits.

Hope this helps.

i tried using the follwing command in hbase shell

>> put
>> 'Test','\x03\x00\x00\x00\x0A\x00\x00\x01:K\xF0\xC0@IN\x00\x00AS*******','C:input','25'

but, row key length is 292 bytes its a composite key combination of
time_seg+date+country_id+****+metrics_id (15 fields)

it is stored in the correct region '\x03'

and im converting all the above field values into  byte in java program and
using the Put java api to insert the value to the hbase

but, it get stored in the first region '\x01'

i dont know why its happening when using java api
plz help

Your translation of region name must be incorrect.  It can be tricky
going from the String representation to the raw bytes.

Can you do something like figure out its ordinal position in .META.
then scan .META.  The rows in .META. are regionnames.  You can take
the Nth row in the .META. and use its bytes as the region name doing
your manipulations?
