splitPoint parameter in splitRegionAsync
Hi Users,
I found that when we start to split region, used splitRegionAsync in
HbaseAdmin.
it only check whether the splitPoint is startkey or not.
should we also check splitPoint is endkey ?
Thanks.
Kevin

hi stack,
In the hbase/client/HBaseAdmin.java : https://goo.gl/hojSM3
<https://goo.gl/hojSM3>
Future<Void> splitRegionAsync(RegionInfo hri, byte[] splitPoint)
throws IOException {
TableName tableName = hri.getTable();
if (hri.getStartKey() != null && splitPoint != null &&
Bytes.compareTo(hri.getStartKey(), splitPoint) == 0) {
throw new IOException("should not give a splitkey which equals
to startkey!");
}
...
...
Thanks,
Kevin

That sounds right Kevin. Mind adding pointer to where in the code you are
referring to?

The end key of one region is the start key of the next so cecking the
startkey is sufficient?
Thanks Kevin,
