Michael Stack reopened HBASE-25361:
-----------------------------------

Reopen to apply addendum. Test just failed on me. Looking at my PR again, I'm missing reset of a counter so the new wait actually doesn't happen. Here is the addendum:

 

commit 7d0a687e5798a2f4ca3190b409169f7e17a75b34 (HEAD -> m, origin/master, origin/HEAD)

HBASE-25361 [Flakey Tests] branch-2 TestMetaRegionLocationCache.testStandByMetaLocations (#2736)
 Addendum; Reset counter so we actually wait in the new loop added by the
 above.

> This just happened to me running tests locally. I see it in the current flakies list [https://ci-hadoop.apache.org/job/HBase/job/HBase-Flaky-Tests/job/branch-2/310/testReport/junit/org.apache.hadoop.hbase.client/TestMetaRegionLocationCache/testStandByMetaLocations/]
>  
> It looks like a simple timing issue. Let me put up a simple patch to see if it helps.
