Duo Zhang commented on HBASE-25215:
-----------------------------------
I think the problem is that, when we add delay for scan, we will also fail the
locating operation as it is also a scan on meta table, so the exception will be
TimeoutIOException as when locating we use a different timeout setting. But if
we have already cached the location in cache, then we will get a
CallTimeoutException directly, which causes the test to fail.
> TestClientOperationTimeout.testScanTimeout is flaky
