> Key: HBASE-30251
> URL: https://issues.apache.org/jira/browse/HBASE-30251
> Project: HBase
> Issue Type: Sub-task
> Components: Scanners, test
> Reporter: Duo Zhang
> Assignee: Duo Zhang
> Priority: Major
>
> On branch-3+, the default implementation for ResultScanner will be an async
> prefetch one, so without proper settings, calling next in foreground may lead
> to lots of rpc next calls in background, and mess up the tests.
