Andrew Purtell commented on HBASE-20940:
----------------------------------------
I should have some time later today. I can revert your old change, apply your
latest patch, then make an addendum diff by comparing it with the upstream
tracking branch. (FYI, if you want to try this trick going forward). If all
tests pass for me I will commit the addendum. Will be back later with an update.
> HStore.cansplit should not allow split to happen if it has references

> When split happens and immediately another split happens, it may result into
> a split of a region who still has references to its parent. More details
> about scenario can be found here HBASE-20933
> HStore.hasReferences should check from fs.storefile rather than in memory
> objects.
