      Description

      $geoNear pipeline within aggregate command always logs a warning about deprecated option "uniqueDocs" (see below), even if that option has never been set or used.

      mongodb.log:

      warning: mydb.timezone: ignoring deprecated uniqueDocs option in geoNear command

      As I get right, aggregation command calls first GeoNear command with always set "uniqueDocs" option.

      See https://github.com/mongodb/mongo/blob/r2.6.9/src/mongo/db/pipeline/document_source_geo_near.cpp#L139
