----------------------------------------
Summary: Use EnvironmentEdgeManager to compute clock skew in Master
Key: HBASE-24446
URL: https://issues.apache.org/jira/browse/HBASE-24446
Project: HBase
Issue Type: Bug
Affects Versions: 1.6.0
Reporter: Sandeep Guggilam
Assignee: Sandeep Guggilam
Fix For: 3.0.0-alpha-1, 1.7.0, 2.4.0
There are few cases where the Master is not able to complete the initialization
as it waiting for the region server to report to it. The region server actually
reported to the master but the master rejected the request because of clock
skew issue though both of them are on same JVM
The Region server uses EnvironmentEdgeManager.currentTime to report the current
time and HMaster uses System.currentTimeMillis() to get the current time for
computation against the reported time by RS. We should also just use
EnvironmentEdgeManager even in Master as we are expected not to use
System.currentTime directly and instead go through EnvironmentEdgeManager
