Hi shaofengshi,
You get my point, and here is my opinion for two comments,:
1. I consider Embedded `try-catch` is a compromise plan, or it would modify
more code.
2. `IOException` maybe a more smarter choice, but after reading hbase source
code `RetriesExhaustedException` is the one exception that need to recheck.

> KYLIN use hbase to persist resouce metadata. When hbase rpc timeout, kylin
> would rollback the resource timestamp. It caused resource inconsistent
> between kylin's memory and hbase if hbase already put the resource.
