在Hector，Cassandra中调用方法“ addEqualsExpression”时出现错误

| 您好，开发人员，运行上述代码时出现错误：

public void getConditioningQuery(String columnName,String value){
        QueryResult<OrderedRows<String, String, String>> result =
        (QueryResult<OrderedRows<String, String, String>>) new IndexedSlicesQuery<String, String, String>(keyspace, serializer, serializer, serializer)
        .addEqualsExpression(\"state\", \"TI\")
        .setReturnKeysOnly()
        .setColumnFamily(CF_NAME)
        .setStartKey(\"\")
        .execute();
        System.out.println(\"Result=\"+result.get().getList());
    }

此方法是查找state = TI的行。我在我的列族中添加了索引，如果我在cassandra-cli中手动查询，则显示数据，但是如果我使用hector代码，则出现此错误：在我的IDE =

345 [main] INFO me.prettyprint.cassandra.service.JmxMonitor - Registering JMX me.prettyprint.cassandra.service_MyCluster:ServiceType=hector,MonitorType=hector
867 [main] INFO me.prettyprint.cassandra.hector.TimingLogger - start[1306754734185] time[91] tag[WRITE.success_]
10926 [main] INFO me.prettyprint.cassandra.hector.TimingLogger - start[1306754734314] time[10021] tag[READ.fail_]
me.prettyprint.hector.api.exceptions.HTimedOutException: TimedOutException()
        at me.prettyprint.cassandra.service.ExceptionsTranslatorImpl.translate(ExceptionsTranslatorImpl.java:32)

并且在cassandra log =

ERROR 18:25:34,326 Fatal exception in thread Thread[ReadStage:102,5,main]
java.lang.AssertionError: No data found for NamesQueryFilter(columns=) in DecoratedKey(165611378069681836494944905825187619237, 73616e6a6f7578):QueryPath(columnFamilyName=\'user\', superColumnName=\'null\', columnName=\'null\') (original filter NamesQueryFilter(columns=)) from expression \'user.state EQ TI\'

即时消息之所以如此混乱，是因为错误告诉您是否未找到列族用户的列中的数据，但是如果即时消息使用cassandra-cli，则会显示该数据。即时通讯如此混乱，仍然停留在这里..也许我的方法是错误的？有人可以帮我告诉我什么地方错了吗？即时通讯仍然用谷歌来解决这个问题..感谢您的关注，对不起我的英语不好：D ..
