*Steps to reproduce*
# Create a {{LOCAL}} user account (using either the Ambari UI or REST API)
{noformat}
POST /api/v1/users
{noformat}
{code:title=Payload}
{
"Users" : {
"user_name" : "myuser",
"password" : "hadoop"
}
}
{code}
# Change the user's password (using either the Ambari UI or REST API via the
users entry point)
{noformat}
PUT /api/v1/users/myuser
{noformat}
{code:title=Payload}
{
"Users" : {
"old_password" : "hadoop"
"password" : "hadoop1234"
}
}
{code}
{code:title=Response}
{
"status" : 500,
"message" : "org.apache.ambari.server.controller.spi.SystemException: An
internal system exception occurred: java.lang.Long cannot be cast to
java.lang.String"
}
{code}
*Cause*
When building the internal request to set the user's password via the
UserAuthenticationSource resource provider, the authentication source key is
set as a {{Long}}. The UserAuthenticationSource resource provider expects this
value to be a {{String}}.
*Solution*
The UserAuthenticationSource resource provider should accept the
{{AuthenticationSourceInfo/source_id}} as either a {{Numeric}} or a {{String}}
value that ultimately translates to a {{Long}}.
