----------------------------------------
[~jingchengdu], thanks for taking a look.
I've isolated the lines of code that cause the test failures -- fixing it one
way breaks TestHRegionServerBulkLoad and the other breaks a bulk loading mob
test. I'm digging in to figure this out before i push the merge.
Here's the code in DefaultCompactor (args are backwards in trunk!)
{code}
writer = store.createWriterInTmp(fd.maxKeyCount, this.compactionCompression,
true,
- true, fd.maxTagsLength > 0);
+ fd.maxTagsLength > 0, true);
boolean finished =

> It's quite useful to save the medium binary data like images, documents
> into Apache HBase. Unfortunately directly saving the binary MOB(medium
> object) to HBase leads to a worse performance since the frequent split and
> compaction.
> In this design, the MOB data are stored in an more efficient way, which
> keeps a high write/read performance and guarantees the data consistency in
> Apache HBase.
