>                 Key: HBASE-2899
>                 URL: https://issues.apache.org/jira/browse/HBASE-2899
>             Project: HBase
>          Issue Type: Bug
>            Reporter: Lars Francke
>            Priority: Trivial
> There is a property in hbase-default.xml called {{hfile.min.blocksize.size}} set to {{65536}}.
> The description says: Minimum store file block size.  The smaller you make this, the
 bigger your index and the less you fetch on a random-access.  Set size down  if you have
small cells and want faster random-access of individual cells.
> This property is only used in the HFileOutputFormat and nowhere else. So we should at
least change the description to something more meaningful.
> The other option I see would be: HFile now has a DEFAULT_BLOCKSIZE field which could
be moved to HConstants and HFile could somehow read the {{hfile.min.blocksize.size}} from
the Configuration or use HConstansts.DEFAULT_BLOCKSIZE if it's not defined. I believe this
is what's happening to the other config variables?
