hfile.min.blocksize.size
------------------------
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?
