> --------------------------------------------------------

> Key: HBASE-9898
> URL: https://issues.apache.org/jira/browse/HBASE-9898
> Project: HBase
> Issue Type: Improvement
> Reporter: Jean-Daniel Cryans
>
> I was exploring if there would be a nice way to set the compression by
> default to a different algorithm but I didn't find any that I can implement
> right now, dumping my ideas so that others can chime in.
> I think the best place to take it into account would be on the master's side.
> Basically you run a check when creating a new table to see if compression
> wasn't set, and if so then set it to the new default. The important thing is
> you don't want to replace NONE, because that might be the user's goal to set
> it like that.
> The main problem is that the normal HCD constructor calls the deprecated
> constructor that sets most of the properties to their defaults, including
> compression, which means that it will always be NONE instead of null.
> It appears that this constructor has been deprecated since February 2012
> (https://github.com/apache/hbase/blame/0.94/src/main/java/org/apache/hadoop/hbase/HColumnDescriptor.java#L292)
> so maybe we can remove it in the next major version and make our life easier?
