…#11939) When a log entry is appended to a Kafka topic using KafkaLog4jAppender, the producer.send operation may hit a deadlock if the producer network thread also tries to append a log at the same log level. This issue is triggered when idempotence is enabled for the KafkaLog4jAppender and the producer tries to acquire the TransactionManager lock. This is a temporary workaround to avoid deadlocks by disabling idempotence explicitly in KafkaLog4jAppender. Reviewers: Luke Chen <showuon@gmail.com>, Ismael Juma <ismael@juma.me.uk>
