Last_Error: Relay log read failure: Could not parse relay log event entry. The possible reasons are: the master’s binary log is corrupted (you can check this by running ‘mysqlbinlog’ on the binary log), the slave’s relay log is corrupted (you can check this by running ‘mysqlbinlog’ on the relay log), a network problem, or a bug in the master’s or slave’s MySQL code. If you want to check the master’s binary log or slave’s relay log, you will be able to know their names by issuing ‘SHOW SLAVE STATUS’ on this slave.
Error Solution — Verify IAM user account have “CloudWatchFullAccess” policy attached. — Verify “AWSAccessKeyId” and “AWSSecretKey” are correctly placed inside the config file “awscreds.conf“. like below i.e. without any single or double quote.
