> Here is my case. After repeatedly minor compaction, the size of storefile is very large.
Compaction with large storefile will waste much bandwidth, so i use the “hbase.hstore.compaction.max.size”
to skip this case. But after use this config, i find that major compaction will be skipped
forever when i read the source code and the deletes and muti-versions data my waste storage.
So i had to modify the code. 
> Now i'm try to submit my patch.But my patch is not perfect. I think there should be an
other config to determine if the large size storefile should join major compaction in HColumnDescriptor.
