[jira] [Updated] (SPARK-12191) Support "." character in DataFrame
column name for ML
[ https://issues.apache.org/jira/browse/SPARK-12191?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Yanbo Liang updated SPARK-12191:
--------------------------------
Description:
Currently if you specify the inputCol/outputCol with names which include dot, it will throw exceptions.
We should support "." character in DataFrame column name for ML.
Meanwhile, we can change the SparkR mllib examples to use "Sepal.Length" rather than "Sepal_Length".
