错误点:FATAL org.apache.hadoop.hbase.regionserver.HRegionServer: Master rejected startup because clock is out of sync
org.apache.hadoop.hbase.ClockOutOfSyncException: org.apache.hadoop.hbase.ClockOutOfSyncException: Server hadoopslave2,60020,1372320861420 has been rejected; Reported time is too far out of sync with master. Time difference of 143732ms > max allowed of 30000ms
原因:时间不一致造成的
解决方案1:
配置:hbase.master.maxclockske
<property>
<name>hbase.master.maxclockskew</name>
<value>200000</value>
<description>Time difference of regionserver from master</description>
</property>
