HBase partitions it's tables across region servers. See :
- How HBase partitions table across regionservers?

I am not sure how random or far apart your random key should be to be able to write to different partitions.
See discussions on hbase.hregion.max.filesize and base.hregion.maxfilesize which suggests that tables are split to new regions when the appropriate data size has been reached.
