// 测试题目 1 (答案期望 1)
问题：一个圆台形的木块，上、下底面的半径分别为 4 和 8，高为 3，用它加工成一个与圆台等高的四棱台，棱台下底面为一边长等于 9 的矩形，且使其体积最大。
现再从余下的四块木料中选择一块车削加工成一个球，则所得球的半径最大值是？（加工过程中不计损耗）

// 测试题目2 (答案期望是 1/80)
Let x_i be the positive real roots of the equation
\cos x \cosh x + 1 = 0.
Find the value of
\sum_{i=1}^{+\infty} x_i^{-6} \left( \frac{\sin x_i - \sinh x_i}{\cos x_i + \cosh x_i} \right)^2.
You must answer me in Chinese.

Server运行一段时间后写入Hbase提示Cell过大的问题

Server运行一段时间后, 导入数据突然出现提示大量Hbase单Cell超过10Mb的异常, 导入任何数据源都可以触发, 不管是覆盖写入还是更新写入 并且数据源确认没有过长的数据, 而且重启Server之后, 这个错误就不报了... :(

怀疑是HG-Server运行时间长了之后什么隐蔽的问题导致, 但是不确定如何定位.
