> Ability to configure timeout between RPC retry to RS from master
> ----------------------------------------------------------------
>
> Key: HBASE-24511
> URL: https://issues.apache.org/jira/browse/HBASE-24511
> Project: HBase
> Issue Type: Bug
> Reporter: Sandeep Guggilam
> Assignee: Sandeep Guggilam
> Priority: Major
> Fix For: 3.0.0-alpha-1, 2.3.0, 2.2.6
>
>
> This is useful for the cases where there is an injected environment edge and
> when the first RS RPC request fails causing it to go to the retry block.
> In the absence of this , the default timeout would be set to 100 ms and the
> DelayedUtil class is meant to execute the retry after 100 ms. However as per
> the getRemainingTime() logic here
> (https://github.com/apache/hbase/blob/5b01e613fbbb92e243e99a1d199b4ffbb21ed2d9/hbase-procedure/src/main/java/org/apache/hadoop/hbase/procedure2/util/DelayedUtil.java#L94),
> the equation would be evaluated to
>
> EnvironmentEdgeManager.currentTime() >= EnvironmentEdgeManager.currentTime()
> + 100 which would never get evaluated to true in case of injected edge and
> retry never happens. Hence this config helps you to override it to 0 in cases
> we want to test with a manual injected environment edge so that the retry
> would succeed
>
> An example would be Master trying to open the meta region even before the RS
> is online, In this case the retry of opening the meta region would never
> happen in the case of injected environment edge and master would never finish
> the initialization
