[jira] [Created] (HBASE-30251) Async prefetch cause TestClientScannerTimeouts flaky

Duo Zhang created HBASE-30251:
---------------------------------

             Summary: Async prefetch cause TestClientScannerTimeouts flaky
                 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


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.
