Ok. I think the evict() is ensuring thread safety by using a concurrent map.  I am +1 on this.  Thanks for the perseverance.

> The read/write MOB in HBase are implemented in this JIRA. Normally, the Cells are saved in the MemStore, and flushed to the HFiles when necessary. For MOB, the Cells are saved in the MemStore as well, but they're flushed to elsewhere out of HBase in the format of HFiles.
