Script modify：
117 # This file and variable seems to have no effect and probably should be deleted
118 #XTRABACKUP_PID=$(mktemp --tmpdir wsrep_sst_xtrabackupXXXX.pid)
119 XTRABACKUP_PID=$(mktemp -p ${TMPDIR} wsrep_sst_xtrabackupXXXX.pid)

May be I command version problem?

[Raghavendra D Prabhu (raghavendra-prabhu)]

mktemp uses $TMPDIR or /tmp (in that order) if --tmpdir is
provided and that is used as relative path to the path fragment
generated from wsrep_sst_xtrabackupXXXX.pid

Do you have permission issues with /tmp?

You can check /DATA/data_node//innobackup.backup.log for the
directory it used.

mktemp version is 1.5 in Oracle Linux Server release 5.7，this version haven't paramter --tmpdir.
