[jira] [Updated] (SPARK-28163) Kafka ignores user configuration on FETCH_OFFSET_NUM_RETRY and FETCH_OFFSET_RETRY_INTERVAL_MS

["Gabor Somogyi (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/SPARK-28163?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Gabor Somogyi updated SPARK-28163:
----------------------------------
    Description: 
There are "unsafe" conversions in the Kafka connector.
CaseInsensitiveStringMap comes in which is then converted the following way:
{code:java}
...
options.asScala.toMap
...
{code}
The main problem with this is that such case it looses its case insensitive nature
(case insensitive map is converting the key to lower case when get/contains called).
