install knox error. IndexError: list index out of range

问题

After upgrading from HDP 2.7 to HDP 3.1, I manually uninstalled many services, such as spark2,hive,hbase and Knox, for some reason.

When I tried to install Knox, the installation failed.

env:

ambari 2.7

HDP 3.1

enabled kerberos

used openldap

What caused this problem?

What should I do?

Thanks for helping me.
