We study theoretically the transport of linearly polarized exciton-polaritons in a quasi one-dimensional mi- crocavity channel separating two polariton condensates generated by optical pumping. The direction and value of mass and spin current are controlled by the relative phase and polarisation of the two condensates, as in the stationary Josephson effect. However, due to dissipation and particle-particle interactions, the current denisty is inhomogeneous: it strongly depends on the coordinate along the channel axis. A stationary spin domain can be created in the channel, its position would be sensitive to the phase difference of two bordering condensates.
