内网环境中三台hbase机器性能不好，机器反应慢，在使用过程中因为超时导致了一些操作失败。
因此需调整超时时间，默认为60秒，在配置文件 hbase-site.xml中：
<property>
<name>hbase.rpc.timeout</name>
<value>600000</value>
</property>
<property>
<name>hbase.client.operation.timeout</name>
<value>600000</value>
</property>
<property>
<name>hbase.client.scanner.timeout.period</name>
<value>600000</value>
</property>
<property>
<name>hbase.regionserver.lease.period</name>
<value>600000</value>
</property>
<property>

<value>600000</value>
</property>
<property>
