Apekshit Sharma commented on HBASE-7105:
----------------------------------------
I believe that would be wrong thing to do. If isMajorCompaction() is called
before open(), it may incorrectly report false for a major compacted store
file.

> In StoreFile, we have:
> private AtomicBoolean majorCompaction = null;
> In StoreFile.open(), we do:
> b = metadataMap.get(MAJOR_COMPACTION_KEY);
> if (b != null) {
> // init majorCompaction variable
> }
> Because the file was bulk imported, this is never initialized. Any subsequent
> call to isMajorCompaction() NPE's.
> Fix is to initialize it to false.
