> Add option to toggle CACHE_BLOCKS in count.rb
> ---------------------------------------------
>
> Key: HBASE-25278
> URL: https://issues.apache.org/jira/browse/HBASE-25278
> Project: HBase
> Issue Type: New Feature
> Components: shell
> Reporter: Josh Elser
> Assignee: Josh Elser
> Priority: Minor
> Fix For: 3.0.0-alpha-1, 2.4.0
>
>
> A trick I've found myself doing a couple of times (hat-tip to [~psomogyi]) is
> to edit table.rb so that the `count` shell command will not instruct
> RegionServers to not cache any data blocks. This is a quick+dirty way to
> force a table to be loaded into block cache (i.e. for performance testing).
> We can easily add another option to avoid having to edit the ruby files.
