-----------------------------------

hi, [~jingcheng.du@intel.com]

Does hbase bulkload support MOB? There is no mob file in the hdfs path '/hbase/mobdir/data' in my test. This is my test step:

1/ create hfile by mapreduceHFileOutputFormat2.configureIncrementalLoad

2/ LoadIncrementalHFiles.doBulkLoad

>   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.
