kevin su commented on HBASE-22108:
----------------------------------
maybe we could add moveRandom(byte[] encodedRegionName) method in Admin
btw, there is split(TableName tableName) method, user don't need to pass null.
> Avoid passing null in Admin methods

> Key: HBASE-22108
> URL: https://issues.apache.org/jira/browse/HBASE-22108
> Project: HBase
> Issue Type: Task
> Components: Admin
> Reporter: Duo Zhang
> Priority: Major
>
> For some methods we must pass null if we want specific behaviors, for
> example, move region to a random server, split region without providing an
> explicit split point, etc.
> We should provide methods without some parameters so user do not need to pass
> null.
> So in the future users do not need to guess whether a method accept null
> parameters, the answer is always no.
