For scanHBase094Table():
baseDefaults.addResource("hbase094_hbase_default.xml");
where hbase.rootdir points to file://
How is the user supposed to plug in hbase-site.xml for the 0.94 cluster ?
For TableMigrationManager, I don't see where setBatchSize() is called. Does
this mean that batch size of 0 would be in effect ?
Do you use any API specific to 1.2.4 ? Otherwise I suggest renaming hbase124
as hbase1 since 1.x releases are compatible.
Thanks
