Mikael Sitruk commented on HBASE-4902:
--------------------------------------
In the following way
// assume that we get maxRange and presplitNumber as parameters
// in our case 13000000 and 1000 respectively
long delta = maxRange / m_presplitNumber;
long currentValue = 0;
byte[][] splits = new byte[m_presplitNumber - 1][];
for (int index = 0; index < splits.length; ++index)
{
currentValue += delta;
String key = keyPrefix + (currentValue - 1);
m_logger.info(String.format("split for key %s\n", key));
splits[index] = key.getBytes();
}
return splits;
Then i call
hba.createTable(htableDesc, splits);
Into the log i have:
...

> Key: HBASE-4902
> URL: https://issues.apache.org/jira/browse/HBASE-4902
> Project: HBase
> Issue Type: Bug
> Affects Versions: 0.90.2
> Reporter: Mikael Sitruk
>
> i have 13 millions keys, I use presplit of 1000 regions.
> while looking at the regions created, i see
> Region Name : TC,sub_10386999,1322603111143.5b36001298f3dab177edf3a7265c628a.
> Start Key: sub_10386999
> End Key: sub_103999
> That is instead sub_10386999 + 13000 = sub_10399999 the ui will only show
> sub_1039999 (missing last 9 digit)
> It occurs in several place in different region
> for another key also:
> Start: sub_4406999
> End: sub_441999
> instead of sub_4419999
