如何从Bigtable逐行键中获取所有值？

Question

我无法从BigTable逐行键中获得所有的值，

我的表看起来是这样的，我只能得到其中的3个，同一个列家族具有相同的限定符只能得到一个，例如散列:md5只会得到"emialmd5test“。

  hashes:md5                               @ 2019/06/17-16:57:10.173000
    "emialmd5test"
  hashes:md5                               @ 2019/06/17-10:58:39.711000
    "emialmd5"
  hashes:sha1                              @ 2019/06/17-16:57:10.173000
    "emailsha1test"
  hashes:sha1                              @ 2019/06/17-10:58:39.711000
    "emailsha1"
  hashes:sha256                            @ 2019/06/17-16:57:10.172000
    "emailsha256test"
  hashes:sha256                            @ 2019/06/17-10:58:39.711000
    "emailsha256"

这是我的密码

Connection connection = BigtableConfiguration.connect(WholeSaleHelper.WHOOLE_SALE_CONFIG.toHBaseConfig());
    Scan scan = new Scan()
        .setRowPrefixFilter(cookieAndPel.getValue().getBytes());

    Table table = connection.getTable(TableName.valueOf(WholeSaleHelper.WHOOLE_SALE_CONFIG.getTableId()));
    byte[] md5Bytes = null, sha1Bytes = null, sha256Bytes = null;

    for (Result result : table.getScanner(scan)) {

      md5Bytes = result.getValue(WholeSaleHelper.WHOLE_SALE_COLUMN_FAMILY.getBytes(), WholeSaleHelper.WHOLE_SALE_MD5.getBytes());
      sha1Bytes = result.getValue(WholeSaleHelper.WHOLE_SALE_COLUMN_FAMILY.getBytes(), WholeSaleHelper.WHOLE_SALE_SHA1.getBytes());
      sha256Bytes = result.getValue(WholeSaleHelper.WHOLE_SALE_COLUMN_FAMILY.getBytes(), WholeSaleHelper.WHOLE_SALE_SHA256.getBytes());
    }

或者我可以用其他方法得到值吗？只需按roe键搜索即可获得所有值。不关心列族和限定符

您可以将此添加到扫描中，以获得所有版本：scan.setMaxVersions();
