本文整理了Java中org.apache.hadoop.hbase.KeyValue.toString()方法的一些代码示例，展示了KeyValue.toString()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。KeyValue.toString()方法的具体详情如下：
包路径：org.apache.hadoop.hbase.KeyValue
类名称：KeyValue
方法名：toString

KeyValue.toString介绍

[英]Produces a string map for this key/value pair. Useful for programmatic use and manipulation of the data stored in an WALKey, for example, printing as JSON. Values are left out due to their tendency to be large. If needed, they can be added manually.

@Test
public void testBasics() throws Exception {
 LOG.info("LOWKEY: " + KeyValue.LOWESTKEY.toString());
 String name = "testBasics";
 check(Bytes.toBytes(name),
  Bytes.toBytes(name), Bytes.toBytes(name), 1,
  Bytes.toBytes(name));
 // Test empty value and empty column -- both should work. (not empty fam)
 check(Bytes.toBytes(name), Bytes.toBytes(name), null, 1, null);
 check(HConstants.EMPTY_BYTE_ARRAY, Bytes.toBytes(name), null, 1, null);
 // empty qual is equivalent to null qual
 assertEquals(
  new KeyValue(Bytes.toBytes("rk"), Bytes.toBytes("fam"), null, 1, (byte[]) null),
  new KeyValue(Bytes.toBytes("rk"), Bytes.toBytes("fam"),
   HConstants.EMPTY_BYTE_ARRAY, 1, (byte[]) null));
