-----------------------------------------
    Resolution: Not A Problem

> Importing rows with bulkupload can overload single regionservers

>                 Key: HBASE-13034
>                 URL: https://issues.apache.org/jira/browse/HBASE-13034
>             Project: HBase
>          Issue Type: Improvement
>          Components: mapreduce
>    Affects Versions: 0.98.0
>            Reporter: Bryant Khau
>            Priority: Minor
>
> Exporting a table with a common schema, like hashes as the key, will result 
> in a sorted exported file. When imported with 
> org.apache.hadoop.hbase.mapreduce.Import, region servers can be overloaded 
> one by one by requests by the MapReduce job, since the rows are imported in 
> sequential order, and a regions span ranges in sequential order. This is more 
> likely to happen with lots of data and not a lot of regions.
