Busy - means busy.
Thrown by a region server if it will block and wait to serve a request. For
example, the client wants to insert something to a region while the
region is compacting.
You should avoid this. If you can't :
* Reduce # of M/R tasks.
* Disable major compaction
* Disable region splitting
* Increase max region size.
* Add retry logic to the client (M/R task).
Check bulk loading.
