Users named "ignite" cannot change their password?

Hi,

Execute the following statement:
ALTER USER ignite WITH PASSWORD 'test123';

The error message is as follows:

SQL 错误 [1] [50000]: Operation failed 
[nodeId=88b03674-04a4-44cb-bd42-8f2ed1e980ff,

org.apache.ignite.internal.processors.authentication.UserManagementException: 
User doesn't exist [userName=IGNITE]]

The password of other users can be changed.
