["Hyukjin Kwon (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/SPARK-26921?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Hyukjin Kwon updated SPARK-26921:
---------------------------------
    Description: 
We should update SparkR guide documentation, and some related documents, comments like in {{SQLConf.scala}} when most of tasks are finished


  was:
Arrow optimization was added but Arrow is not available on CRAN.

So, it had to add some hacks to avoid CRAN check in SparkR side. For example, see 

https://github.com/apache/spark/search?q=requireNamespace1&unscoped_q=requireNamespace1

These should be removed to properly check CRAN in SparkR
