HBaseTestingUtility.createTable介绍

[英]Create a table.
[中]创建一个表。

代码示例

代码示例来源：origin: apache/hbase

private Table createTable(boolean multiRegions) throws IOException {
 if (multiRegions) {
  return UTIL.createTable(NAME, CF, new byte[][] { Bytes.toBytes(1) });
 } else {
  return UTIL.createTable(NAME, CF);
 }
}

@Test
public void testCreateMultiRegion() throws IOException {
 byte[] end = { 1, 3, 5, 7, 9 };
 byte[] start = { 0, 2, 4, 6, 8 };
 byte[][] f = { Bytes.toBytes("f") };
 TEST_UTIL.createTable(tableName, f, 1, start, end, 10);
}
