 Description   

User reported the plugin directory isn't picked as default location so throws the following error:

Connection to [rnpans401]:9611 failed. Error 1045: Plugin dialog could not be loaded: /home/timofey_turenko_mariadb_com/MaxScale/_build/connector-c/install/lib/mariadb/plugin/dialog.so: cannot open shared object file: No such file or directory

To workaround the issue, 

[root@host1 ~]# mkdir /home/timofey_turenko_mariadb_com
 
 
 
[root@host1 ~]# mkdir /home/timofey_turenko_mariadb_com/MaxScale
 
[root@host1 ~]# mkdir /home/timofey_turenko_mariadb_com/MaxScale/_build
 
[root@host1 ~]# mkdir /home/timofey_turenko_mariadb_com/MaxScale/_build/connector-c
 
[root@host1 ~]# mkdir /home/timofey_turenko_mariadb_com/MaxScale/_build/connector-c/install
 
[root@host1 ~]# mkdir /home/timofey_turenko_mariadb_com/MaxScale/_build/connector-c/install/lib
 
[root@host1 ~]# mkdir /home/timofey_turenko_mariadb_com/MaxScale/_build/connector-c/install/lib/mariadb
 
[root@host1 ~]# mkdir /home/timofey_turenko_mariadb_com/MaxScale/_build/connector-c/install/lib/mariadb/plugin
 
[root@host1 ~]#
 
[root@host1 ~]# cp /usr/lib64/mysql/plugin/dialog.so /home/timofey_turenko_mariadb_com/MaxScale/_build/connector-c/install/lib/mariadb/plugin
 
[root@host1 ~]#
 
[root@host1 ~]#
 
[root@host1 ~]# chmod 755 /home/timofey_turenko_mariadb_com/MaxScale/_build/connector-c/install/lib/mariadb/plugin/*
 
[root@host1 ~]# ls -lrht /home/timofey_turenko_mariadb_com/MaxScale/_build/connector-c/install/lib/mariadb/plugin/dialog.so
 
-rwxr-xr-x 1 root root 11K Sep 14 07:40 /home/timofey_turenko_mariadb_com/MaxScale/_build/connector-c/install/lib/mariadb/plugin/dialog.so

Then, error went away.

This seems to be a regression in certain components as the compile time default is used. MaxScale should always pass the plugin directory to the connector whenever it opens a connection as the compile time one is always wrong.
