We present an exact black hole solution in the Klebanov-Tseytlin geometry [hep-th/0002159]. Our solution realizes Maldacena dual of the finite temperature N=1 duality cascade of [hep-th/0007191] above the temperature of the chiral symmetry breaking. We compare the Bekenstein-Hawking entropy of the black hole with the entropy of the SU(N+M)xSU(N) gauge theory.25 pages, LaTeX, v2:references added, v3:error identified that led to the incorrect conclusion.
