* A map/reduce program that estimates the value of Pi
* using a quasi-Monte Carlo (qMC) method.
* Arbitrary integrals can be approximated numerically by qMC methods.
* In this example,
* we use a qMC method to approximate the integral $I = \int_S f(x) dx$,
* where $S=[0,1)^2$ is a unit square,
* $x=(x_1,x_2)$ is a 2-dimensional point,
* and $f$ is a function describing the inscribed circle of the square $S$,
* $f(x)=1$ if $(2x_1-1)^2+(2x_2-1)^2 <= 1$ and $f(x)=0$, otherwise.
* It is easy to see that Pi is equal to $4I$.
* So an approximation of Pi is obtained once $I$ is evaluated numerically.
* * There are better methods for computing Pi.
* We emphasize numerical approximation of arbitrary integrals in this example.
* For computing many digits of Pi, consider using bbp.
*
* The implementation is discussed below.
*
* Mapper:
* Generate points in a unit square
* and then count points inside/outside of the inscribed circle of the square.
*
* Reducer:
* Accumulate points inside/outside results from the mappers.
*
* Let numTotal = numInside + numOutside.
* The fraction numInside/numTotal is a rational approximation of
* the value (Area of the circle)/(Area of the square) = $I$,
* where the area of the inscribed circle is Pi/4
* and the area of unit square is 1.
* Finally, the estimated value of Pi is 4(numInside/numTotal). | 2-dimensional Halton sequence {H(i)},

* Assumptions are the object initialization happens when dir lock is held,
* and inode is valid and is encrypted during initialization.
* <p>
* Namespace changes may happen during re-encryption, and if inode is changed
* the re-encryption is skipped.
