----------------------------------
Summary: 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
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.
