 Description   

If datadir is not specified in the [mysqld] section of the MariaDB configuration file, then mariabackup SST attempts will fail on the joiner with errors in innobackup.move.log similar to this:

170530 12:06:47 innobackupex: Starting the move-back operation
 
 
 
IMPORTANT: Please check that the move-back run completes successfully.
 
           At the end of a successful move-back run innobackupex
 
           prints "completed OK!".
 
 
 
innobackupex based on MariaDB server 10.1.23-MariaDB Linux (x86_64)
 
Error: datadir must be specified.

I believe that this behavior was inherited from the xtrabackup-v2 SST method, but it seems a bit unnecessary and it might be fixable. The server obviously knows its own datadir, so can't it specify the value on the command-line or something like that?

This should be fixed in 10.1.25 and 10.2.7 as part of MDEV-11459 . Thus I am closing this as duplicate.

I am running 10.2.7 on FreeBSD and I am still having this error. I checked the code I built from and it has the fix mentioned here.
