Jean-Daniel Cryans commented on HBASE-4841:
-------------------------------------------
Well the first log is the region offline issue I described, the second one has
data loss indeed but as it was Nov. 21, and providing that it was a recent
checkout, then it would be 4853 yeah.
> If I call split fast enough, while inserting, rows disappear.

> I'll attach a unit test for this. Basically if you call split, while
> inserting data you can get to the point to where the cluster becomes
> unstable, or rows will disappear. The unit test gives you some flexibility
> of:
> - How many rows
> - How wide the rows are
> - The frequency of the split.
> The default settings crash unit tests or cause the unit tests to fail on my
> laptop. On my macbook air, i could actually turn down the number of total
> rows, and the frequency of the splits which is surprising. I think this is
> because the macbook air has much better IO than my backup acer.
