testuser가 kinit및 하고 jdbc로 impala에 접근하는 과정의 로그 기록 내용이다.
testuser@GOOPER.COM 가 kinit을 하면 krbtgt/GOOPER.COM@GOOPER.COM가 AS_REQ가 발생시키며, kinit이 정상적으로 수행후에 testuser@GOOPER.COM가 JDBC접근 과정에서 impala/L4_01.GOOPER.com@GOOPER.COM가 TGS_REQ를 발생시킨다.
초기에 AS_REQ가 여러번 발생한것은 kinit하는 과정에서 패스워드를 여러번 틀려서 발생한것이다.
(패스워드 맞고 안맞고에 상관없이 kinit 명령을 날리는 순간 AS_REQ 가발생한다.)
