Review the list of Streams Replication Manager issues that are resolved in Cloudera Runtime 7.2.15.

CDPD-31745: SRM Control fails to configure internal topic when target is earlier than Kafka 2.3
SRM now creates all internal topics explicitly. SRM also verifies the essential configurations of internal topics at startup, and fails if the topics do not meet the required configurations.
OPSAPS-63104: The automatically generated password for co-located services is invalid
SRM Service Basic Authentication would not work with the default, random generated password. SRM Service Basic Authentication default password is now identical on all SRM Service role instances.

SRM uses the correct ssl.keystore.key configuration when a Kafka External Account specifies the keystore.
