10 errors and 12 warnings

Run tests: xarray/tests/test_concat.py#L135

test_concat_compat FutureWarning: In a future version of xarray the default value for join will change from join='outer' to join='exact'. This change will result in the following ValueError:cannot be aligned with join='exact' because index/labels/sizes are not equal along these coordinates (dimensions): 'y' ('y',) The recommendation is to set join explicitly for this case.

Run tests: xarray/tests/test_concat.py#L228

test_concat_second_empty FutureWarning: In a future version of xarray the default value for compat will change from compat='equals' to compat='override'. This change will result in the following ValueError: Cannot specify both data_vars='different' and compat='override'. The recommendation is to set compat explicitly for this case.

Run tests: xarray/tests/test_concat.py#L268

test_concat_multiple_datasets_missing_vars[False] FutureWarning: In a future version of xarray the default value for data_vars will change from data_vars='all' to data_vars='minimal'. This is likely to lead to different results when multiple datasets have matching variables with overlapping values. To opt in to new defaults and get rid of these warnings now use `set_options(use_new_combine_kwarg_defaults=True) or set data_vars explicitly.

Run tests: xarray/tests/test_concat.py#L493

TestConcatDataset.test_concat_simple[dim1-True-different] FutureWarning: In a future version of xarray the default value for compat will change from compat='equals' to compat='override'. This change will result in the following ValueError: Cannot specify both coords='different' and compat='override'. The recommendation is to set compat explicitly for this case.

This change will result in the following ValueError: Cannot specify both coords='different' and compat='override'. The recommendation is to set compat explicitly for this case.

TestConcatDataset.test_concat_merge_variables_present_in_some_datasets FutureWarning: In a future version of xarray the default value for data_vars will change from data_vars='all' to data_vars='minimal'. This is likely to lead to different results when multiple datasets have matching variables with overlapping values. To opt in to new defaults and get rid of these warnings now use `set_options(use_new_combine_kwarg_defaults=True) or set data_vars explicitly.
