  We present the energy density and flux distribution of a heavy quark moving
through high temperature QCD plasmas and compare them with those in the
strongly coupled N = 4 SYM plasma. The Boltzmann equation is reformulated as a
Fokker-Planck equation at the leading log approximation and is solved
numerically with nontrivial boundary conditions in momentum space. We use
kinetic theory and perform a Fourier transform to calculate the energy and
momentum density in position space. The angular distributions exhibit the
transition to the ideal hydrodynamics and are analyzed with the first and
second order hydrodynamic source. The AdS/CFT correspondence allows the same
calculation at strong coupling. Compared to the kinetic theory results, the
energy-momentum tensor is better described by hydrodynamics even after
accounting for the differences in the shear viscosities. We argue that the
difference between the Boltzmann equation and the AdS/CFT correspondence comes
from the second order hydrodynamic coefficient $\tau_\pi$ which is generically
large compared to the shear length in a theory based on the Boltzmann equation.
