Vishal Khandelwal commented on HBASE-20940:
-------------------------------------------

For check-style: I am getting import order check failure but order seems to be 
correct.

./hbase-server/src/test/java/org/apache/hadoop/hbase/regionserver/TestEndToEndSplitTransaction.java:68:import
 org.junit.AfterClass;: Wrong order for 'org.junit.AfterClass' import. 
[ImportOrder]

For test failure, I reran the test and it worked fine. I have resubmitted the 
patch

For FindBugs, I have fixed and submitted the patch again.(v3)

 

> 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.
