Vladimir Steshin updated IGNITE-13015:
--------------------------------------
Description:
Make sure node failure detection do not use:
{code:java}
System.currentTimeMillis()
and
IgniteUtils.currentTimeMillis()
{code}
We should use nano time instead. Disadventages of current impl.:
1) System time has no quarantine of strict forward movement. System time
can be adjusted, synchronized by NTP as example. This can lead to incorrect and
negative delays.
2) IgniteUtils.currentTimeMillis() is granulated by 10ms
*To fix*:
{code:java}ServerImpl.lastRingMsgReceivedTime{code} should be nano.
