I want to add a task to my server scheduler to run a major compaction for the hbase.
How can I implement this with java code?

It could be either for single region or for all regions.
Can I do the major compaction for some specific tablespaces?

    ...
String tableName = "mytable";
Configuration conf = HBaseConfiguration.create();
conf.addResource(new Path("/home/user/hbase/conf/hbase-site.xml"));

HBaseAdmin admin = new HBaseAdmin(conf);
admin.majorCompact(tableName);
...

    If a table name is given then the compaction will be invoked on all regions of that table.
    Refer to the majorCompact javadoc:

    After invoking this code you’ll find the note “Compacting stores…” under “Currently running tasks” on the Master UI (port 60010 by default)
