Nicolas Liochon commented on HBASE-9983:
----------------------------------------
I haven't done a measure before/after for this one (would have been interested,
I agree).
Right now, so with this jira included, I'm seeing (with Yourkit) that an entry
the location skip list takes ~550 bytes. This will be lowered with HBASE-9976
and HBASE-9988. Then we have one ServerName instance by entry as well...
> Lower the memory footprint of HRegionLocation

> This patch is just about the trivial part
