Subject [jira] [Commented] (HBASE-16775) Flakey test with TestExportSnapshot#testExportRetry and TestMobExportSnapshot#testExportRetry

huaxiang sun commented on HBASE-16775:
--------------------------------------

[~appy] Yeah, passing states across mappers is impossible. I think in the context of the exportSnapshot,
if without retry, we can verify that at destination, there is nothing (clean). If it is retryable,
it will succeed and we can verify that everything is copied over. Going through the code,
it seems that it is not hard to add. I can add that in the test. Thanks.

> The root cause is that conf.setInt("mapreduce.map.maxattempts", 10) is not taken by the
mapper job, so the retry is actually 0. Debugging to see why this is the case.
