> h3. documentation update
> Update the troubleshooting section of the MOB chapter to include a note for "Why is there data over the MOB threshold in the normal {{/hbase/data}} directory rather than in {{/hbase/mobdir}}. List the split-to-hfile feature as one source and bulk loading as another.  Note that in both cases the next compaction to include those files will write the data out to MOB hfiles.
> h3. original
> Steps to reproduce this issue.
> 1. create a table with 1 region, and mob enabled, keep threshold value to 5.
> 2. Load data into the table, keep the value size should be  more than 5.
> 3. flush the table.
> 4. observe the mobdir and data dir, hfiles should be there.
> 5. load data again with different data set, keep the value size is greater than 5.
> 6. Kill -9 RS where table region is online
> 7. Start RS
> check the mob dir and data dir, both should have 2 hfiles each.
> But data dir only have 2 hfiles, that means mob threshold crossed data is considered as normal data.
