Status: Resolved | Priority: Major | Resolution: Not A Problem
Created: 25/Feb/22 13:55
Affects Version/s: 3.2.1

Trying to run any job after bumping our Spark version from 3.1.2 to 3.2.1, lead us to the current exception while reading files on s3:
{code:java}

We found similar problems in the following tickets but:
 - https://issues.apache.org/jira/browse/HADOOP-17017 (we don't use `.` in our bucket names)
 - [https://github.com/aws/aws-sdk-java-v2/issues/1786] (we tried to override it by building Spark with `httpclient:4.5.10` or `httpclient:4.5.8`, with no effect. We also made sure we are using the same `httpclient` version on our main jar).
