从hbase读取时，出现如下错误
Caused by: java.io.IOException: Call to <hostname>.local/<ip address>:60020 failed on local exception: org.apache.hadoop.hbase.ipc.CallTimeoutException: Call id=15, waitTime=59998, operationTimeout=59997 expired.

但是我在代码中使用以下配置来避免时间戳记，因此这些属性不会被覆盖：
hbaseConf.set("hbase.rpc.timeout", "1800000")
hbaseConf.set("hbase.client.scanner.timeout.period", "1800000")
想知道我是否缺少什么。谁能帮忙吗？
