      Description

      Following an upgrade to MariaDB-server-10.2.10-1.el7.centos.x86_64 wsrep_sst_xtrabackup-v2 is unable to initiate an SST to join a node to the cluster.

      It fails with the following errors:

      The root cause appears to be:

      /usr/bin/wsrep_sst_xtrabackup-v2: line 646: WSREP_SST_OPT_PORT: unbound variable
      

      The WSREP_SST_OPT_PORT doesn't have a default value set, either set in wsrep_sst_xtrabackup-v2 or in wsrep_sst_common

      The following diff sets a default value for the WSREP_SST_OPT_PORT variable, and allows the SST to proceed.
