Java LongComparator在带有HBase API的Google Cloud Bigtable中不起作用

我正在尝试构建一些过滤器来过滤Bigtable中的数据。我使用的是

bigtable hbase

驱动程序和hbase驱动程序。实际上，以下是我在

pom.xml

中的依赖项：

    <dependency>
        <groupId>org.apache.hbase</groupId>
        <artifactId>hbase-common</artifactId>
        <version>${hbase.version}</version>
    </dependency>
    <dependency>
        <groupId>org.apache.hbase</groupId>
        <artifactId>hbase-protocol</artifactId>
        <version>${hbase.version}</version>
    </dependency>
    <dependency>
        <groupId>org.apache.hbase</groupId>
        <artifactId>hbase-client</artifactId>
        <version>${hbase.version}</version>
    </dependency>
    <dependency>
        <groupId>org.apache.hbase</groupId>
        <artifactId>hbase-server</artifactId>
        <version>${hbase.version}</version>
    </dependency>

    <dependency>
        <groupId>com.google.cloud.bigtable</groupId>
        <artifactId>bigtable-hbase</artifactId>
        <version>${bigtable.version}</version>
    </dependency>

这样行。但我在前面的代码中添加了以下内容：

Filter filterSalary = new SingleColumnValueFilter(Bytes.toBytes("Salary"), Bytes.toBytes("Salary"),
                CompareFilter.CompareOp.GREATER_OR_EQUAL, new LongComparator(100000));
filters.addFilter(filterSalary);

这给了我一个例外：

Exception in thread "main" com.google.cloud.bigtable.hbase.adapters.filters.UnsupportedFilterException: Unsupported filters encountered: FilterSupportStatus{isSupported=false, reason='ValueFilter must have either a BinaryComparator with any compareOp or a RegexStringComparator with an EQUAL compareOp. Found (LongComparator, GREATER_OR_EQUAL)'}
at com.google.cloud.bigtable.hbase.adapters.filters.FilterAdapter.throwIfUnsupportedFilter(FilterAdapter.java:144)
at com.google.cloud.bigtable.hbase.adapters.ScanAdapter.throwIfUnsupportedScan(ScanAdapter.java:55)
at com.google.cloud.bigtable.hbase.adapters.ScanAdapter.adapt(ScanAdapter.java:91)
at com.google.cloud.bigtable.hbase.adapters.ScanAdapter.adapt(ScanAdapter.java:43)
at com.google.cloud.bigtable.hbase.BigtableTable.getScanner(BigtableTable.java:247)

所以我的问题是如何过滤长数据类型？是hbase问题还是bigtable特有的问题

我发现了这一点，但我无法将我的JAR加载到服务器，因此它不适用于我的情况。

SingleColumnValueFilter支持以下比较器：

• 二进制比较器

• BinaryPrefixComparator

• RegexStringComparator
