hdfs => larger blocks.

How do I make Hbase to write larger hdfs blocks?  I have my
hdfs-site.xml adjusted, and everything restarted, but my region files
still get 64MB allocation.

Yes. The DFS client sets the parameter when the file is created. (In this case HBase.) So the setting needs to be changed in hbase-site.xml or you should symlink your hdfs-site.xml into hbase/conf/.

Best regards,

I did that in hdfs-site.xml, do I need to do it under hbase-site.xml too?

You need to set dfs.block.size which is hadoop parameter.
