# Perform manual shard allocation in the cluster.
#
# Pass the operations you want to perform in the `:body` option. Use the `dry_run` option to
# evaluate the result of operations without actually performing them.
#
# @example Move shard `0` of index `myindex` from node named _Node1_ to node named _Node2_
#
# client.cluster.reroute body: {
# commands: [
# { move: { index: 'myindex', shard: 0, from_node: 'Node1', to_node: 'Node2' } }
# ]
# }
#
# @note If you want to explicitely set the shard allocation to a certain node, you might
# want to look at the `allocation.*` cluster settings.
#
# @option arguments [Hash] :body The definition of `commands` to perform (`move`, `cancel`, `allocate`)
# @option arguments [Boolean] :dry_run Simulate the operation only and return the resulting state
# @option arguments [Boolean] :explain Return an explanation for why the commands can or cannot be executed
# @option arguments [Boolean] :filter_metadata Don't return cluster state metadata (default: false)
#
# @see http://elasticsearch.org/guide/reference/api/admin-cluster-reroute/
