我正在运行Hbase 1.0.1/Hadoop 2.5.2.我正在尝试在桌面上运行扫描,但我正在获得RPC超时.

我已将Hbase RPC超时更改为2分钟,我可以通过UI确认...

<property>
  <name>hbase.rpc.timeout</name>
  <value>120000</value>
  <source>hbase-site.xml</source>
</property>

...但我的客户仍然在60年代后超时......

我已经尝试更改缓存块大小,但这似乎没有任何区别.

还有其他一些我遗漏的超时.表中有很多行(数百万)虽然扫描只返回了数千个,但问题似乎只是一组特定的区域.
