使用Hbase扫描时发生运行时异常

代码：

过滤器过滤器=新的行过滤器（CompareFilter.CompareOp.EQUAL，新 子串比较器（args[1]）

扫描=新扫描（）

scan.setFilter（filter）

ResultScanner res=table.getScanner（扫描）

对于（结果r:res）//第49行

{…}

我运行这个jar，然后得到以下异常消息：

有人能提供一些线索吗？在本例中，您提供的扫描仪正在执行的任务的时间间隔超过了指定的超时时间。（callTimeout=60000，callDuration=60304）

如果您连接到集群，那么您需要优化集群/表/架构以进行读取，或者更改超时，如果您需要进行大量扫描，请选择map reduce。

似乎配置有错误设置您的

参数[1]

是什么？你看过吗？
