Enis Soztutar commented on HBASE-7105:
--------------------------------------
[~clehene] I was reading the code around this, but I failed to understand the
original description for the issue. Bulk loaded files also do create readers,
and hence call open() setting isMajorCompaction field.
Is this a concurrency issue where before this is set, a compaction request can
see the file? Do you have a stack trace or logs showing this state ?
> RS throws NPE on forcing compaction from HBase shell on a single bulk
> imported 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.
