In HBase application development, when the Rowkey range and distribution of a table are known, it is recommended to pre-divide regions. After calling the following code (fragment) to pre-divide a table into regions, this table will create several regions. //Create a table of pre-partitioned regions byte[][] splits=new byte[4][]; splits[0] = Bytes.toBytes("A"); splits[1] = Bytes.toBytes("H"); splits[2] = Bytes.toBytes("O"); splits[3] = Bytes.toBytes("U"); admin.createTable (htd, splits);
