[jira] [Updated] (SPARK-25216) Provide better error message when a
column contains dot and needs backticks quote
[ https://issues.apache.org/jira/browse/SPARK-25216?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Li Jin updated SPARK-25216:
---------------------------
Description:
The current error message is often confusing to a new Spark user that a column containing "." needs backticks quote.
For example, the current message looks like:
{code:java}
Cannot resolve column name "a.b" among (a.b)
{code}
We could improve the error message to, e.g:
{code:java}
Cannot resolve column name "a.b" among (a.b). Try adding backticks to the column name, i.e., `a.b`;
{code}
