does citus support gssapi authentication between coordinator and workers?

[xu james]

hello, 

          I am using citus 10, when  I copy data to a distributed table, I got error

=====

epoll_ctl() failed : No such file or directory

=====

then on worker, I find error in the log

======

provided user name (A) and authenticated username (B) do not match

======

A is the account who copied the data, B is the service account of the coordinator pg service

if I copy the data with account B, it worked 

why does coordinator login worker with the account who issues the copy command?

thanks

James
