hbase Master rejected startup because clock is out of sync 오류 해결방법

총관리자 2016.05.03 11:01 조회 수 : 234

HMaster서버와 HRegionServer간에 시간차이가 30000ms 이상나면 HRegionServer가 기동하지 못하하게 되는데

이때는 서버간의 시간을 맞춰줄 필요가 있다.

rdate -s time.bora.net를 각 서버에서 실행해주면 time.bora.net에서 제공하는 시간으로 동기화 된다.

혹은

ntpdate time.bora.net를 실행한다.
