Missing configuration property when reading NETCDF file

When I open ( snappy.ProductIO.readProduct(SentinelFile)) products saved in NETCDF format (such as SMOS data, “.DBL.nc” extension), I see following warning:

WARNING: org.esa.snap.dataio.netcdf.util.MetadataUtils: Missing configuration property ‘snap.dataio.netcdf.metadataElementLimit’. Using default (100).

How can I fix that? Might it affect any processing steps?

No in general this should not affect any processing.
For some data there are sometimes thousands of elements but are not actually used as metadata or already converted into a tie-point grid.
You can specify this missing property in the snap.properties in the etc folder. Use any value you like.
