Jonathan Hsieh commented on HBASE-15069:
----------------------------------------
Hadoop's FileSystem.get(..) eventually calls this [1] which gets a cached
version. So we may be creating a few extra HFileSystem wrappers around the
same FileSystem instances

> There are a plethora of different static methods sprinkled through out
> HStoreFile and HFile, and many tests that have extraneous calls to 'new
> CacheConfig(conf)' or essentially extraneous FileSystem arguments threaded
> through out the code.
> This patch forces all creation to go through HFile Reader and Writer
> Builders, eliminates all static Builder constructors, and limits the exposure
> Reader/Writers . It also forces all HFile writer uses outside of the
> o.a.h.h.io.hfile package to use the StoreFile writers
