    well, this change avoided the warning but disabled help too (which is 
probably why it's working)
    ```
    > showMethods("attach")
    Function: attach (package base)
    what="ANY"
    what="SparkDataFrame"
    
    > showMethods("fitted")
    Function: fitted (package stats)
    object="ANY"
    object="BisectingKMeansModel"
    object="KMeansModel"
    
    > ?fitted
    Help on topic ‘fitted’ was found in the following packages:
    
      Package               Library
      SparkR                /opt/spark-2.3.0-bin-hadoop2.7/R/lib
      stats                 /usr/lib/R/library
    
    Choose one
    
    1: Get fitted result from a k-means model {SparkR}
    2: Extract Model Fitted Values {stats}
    
    Selection: 0
    > ?attach
    > ?SparkR::fitted
    > ?SparkR::attach
    No documentation for ‘attach’ in specified packages and libraries:
    you could try ‘??attach’
    ```
    basically it shows without asking the base::attach, `?SparkR::attach` 
doesn't work either
