>                 Key: HBASE-17034
>                 URL: https://issues.apache.org/jira/browse/HBASE-17034
>             Project: HBase
>          Issue Type: Bug
>            Reporter: ChiaPing Tsai
>            Priority: Minor
>
> # HTable#exist apply the default consistency, but HTable#existAll dosen’t
> # HTable#existAll may change the passed Gets , but HTable#exist dosen’t. (HTable#get(Get, boolean) clones the passed Get)
> So we have some issues outlined below.
> # Can the passed Get be modified? If so, we can save the clone of Get. If not, the HTable#getScanner() modify the passed Scan for some unset variables, so it is ok to modify the passed Get I guess. 
> # Should we assign the default Consistency to the passed Get which has an null value of Consistency?
> This jira may be solved by [HBASE-16623|https://issues.apache.org/jira/browse/HBASE-16623].
> Any comment? Thanks.
