  A search for a massive resonance decaying into a standard-model-like Higgs
boson (H) and a W or Z boson is reported. The analysis is performed on a data
sample corresponding to an integrated luminosity of 19.7 inverse femtobarns,
collected in proton-proton collisions at a centre-of-mass energy of 8 TeV with
the CMS detector at the LHC. Signal events, in which the decay products of
Higgs, W, or Z bosons at high Lorentz boost are contained within single
reconstructed jets, are identified using jet substructure techniques, including
the tagging of b hadrons. This is the first search for heavy resonances
decaying into HW or HZ resulting in an all-jet final state, as well as the
first application of jet substructure techniques to identify H to WW* to 4q
decays at high Lorentz boost. No significant signal is observed and limits are
set at 95% confidence level on the production cross section of W' and Z' in a
model with mass-degenerate charged and neutral spin-1 resonances. Resonance
masses are excluded for W' in the interval [1.0, 1.6] TeV, for Z' in the
intervals [1.0, 1.1] and [1.3, 1.5] TeV, and for mass-degenerate W' and Z' in
the interval [1.0, 1.7] TeV.
