Description:
When GR is started plugin group_replication reports 'Initialized group communication with configuration' message, something like below:-
2017-12-09T14:37:13.206608Z 12 [Note] [000000] Plugin group_replication reported: 'Initialized group communication with configuration: group_replication_group_name: "71f5607d-dcee-11e7-815e-2816ad2405ae"; group_replication_local_address: "localhost:13010"; group_replication_group_seeds: "localhost:13011,localhost:13010"; group_replication_bootstrap_group: true; group_replication_poll_spin_loops: 0; group_replication_compression_threshold: 1000000; group_replication_ip_whitelist: "AUTOMATIC" group_replication_communication_debug_file: "GCS_DEBUG_TRACE" group_replication_communication_debug_path: "/Narendra/mysql_work/git_repo/mysql-8.0/install/mysql-test/var/mysqld.1/data/"'
Observations:-
1. Options (along with values) in the configuration list are separated by ';' till option 'group_replication_compression_threshold'. Next three options are missing that.
2. 'group_replication_communication_debug_path' doesn't look like a valid option, so should it be displayed here in this message?
How to repeat:
Steps to follow:-
=================
1. ./mtr group_replication.gr_gcs_psi_mutex_cond.test --mysqld=--log-error-verbosity=3
2. $ cd $VARDIR/log/
$ grep -inR "Initialized group communication" mysqld.1.err
