Solution:

Make a accumulo home directory in var/lib

Add the environment variable for accumulo home in the /etc/profile file

[root@ip-xxx ~]# mkdir -p /var/lib/accumulo
[root@ip-xxx~]# vi /etc/profile
[root@ip-xxx ~]# cat /etc/profile|grep 'ACCU'
ACCUMULO_HOME=/var/lib/accumulo
export ACCUMULO_HOME
[root@ip-xxx ~]# source /etc/profile
