HBase KeyValue.getKey() 返回额外字符

以下 hBase 代码在 rowKey 的前面返回一些奇怪的字符：

“\u0000”“\u0014”“ei：虾：-749......”

前面的奇怪字符是“\u0000”和“\u0014”，有时是“\u0016”。我在上面的行中加了引号以使其可读。只有两个，它们被添加到我的 rowkey 之前。密钥应该是“ei:shrimp:-749...”。这是我用来取回密钥的代码：

import static org.apache.hadoop.hbase.util.Bytes.toBytes;

List<KeyValue> kvs = result.list();
        String key = null;
        for (KeyValue kv : kvs) {
            String value = Bytes.toString(kv.getValue());
            String qualifier = Bytes.toString(kv.getQualifier());
            if(key == null) {
                key = Bytes.toString(kv.getKey());

这是我用来创建我的 put 的代码：

public Put createPut(String columnFamily) {
        StringBuilder sb = new StringBuilder(this.getGroup()).append(':');
        sb.append(this.getKey()).append(':').append(this.getCoordinateHash());

        Put p = new Put(toBytes(sb.toString()));
        p = p.add(toBytes(columnFamily), toBytes(COLUMN_VALUE), toBytes(this.getValue()));

知道那些奇怪的字符是什么吗？我做错了什么？谢谢你，拉贾特

原文

the following hBase code returns some weird characters on the front of my rowKey:

"\u0000""\u0014""ei:shrimp:-749…."

The prepended weird characters are '\u0000' and '\u0014', and sometimes '\u0016'. I put quotes in the above line to make it readable. There are only two and they're prepended to my rowkey. The key should be 'ei:shrimp:-749...'. Here is the code that I use to get the keys back:

import static org.apache.hadoop.hbase.util.Bytes.toBytes;

List<KeyValue> kvs = result.list();
        String key = null;
        for (KeyValue kv : kvs) {
            String value = Bytes.toString(kv.getValue());
            String qualifier = Bytes.toString(kv.getQualifier());
            if(key == null) {
                key = Bytes.toString(kv.getKey());

Here is the code I used to create my put:

public Put createPut(String columnFamily) {
        StringBuilder sb = new StringBuilder(this.getGroup()).append(':');
        sb.append(this.getKey()).append(':').append(this.getCoordinateHash());

        Put p = new Put(toBytes(sb.toString()));
        p = p.add(toBytes(columnFamily), toBytes(COLUMN_VALUE), toBytes(this.getValue()));

Any idea what those weird characters are? What am I doing wrong?
Thank you,
