hbase org.apache.hadoop.hbase.ClockOutOfSyncException: org.apache.hadoop.hbase.ClockOutOfSyncException 오류시 조치사항
http://gsda1:16010/master-status를 확인하여 Region Servers부분에 원하는 서버가 포함되지 않으면
로그를 확인해서 아래와 같은 오류가 발생하면서 regionserver의 데몬이 기동하지 않는 경우는
각 서버에서 "rdate -s time.bora.net"를 실행하여 서버의 시간을 동기화 하고 "start-hbase.sh"을 실행하여 재 기동해준다.
(혹은 ntpdate time.bora.net를 실행한다)
