--------------------------------------
Summary: Locale is not handled properly in kafka-consumer
Key: KAFKA-3548
URL: https://issues.apache.org/jira/browse/KAFKA-3548
Project: Kafka
Issue Type: Bug
Components: consumer
Affects Versions: 0.9.0.1
Reporter: Tanju Cataltepe
Assignee: Neha Narkhede
If the JVM local language is Turkish, which has different upper case for the
lower case letter i, the result is a runtime error caused by
org.apache.kafka.clients.consumer.OffsetResetStrategy. More specifically an
enum constant *EARLİEST* is generated which does not match *EARLIEST* (note the
_dotted capital i_).
If the locale for the JVM is explicitly set to en_US, the example runs as
expected.
A sample error log is below:
