Hi,
As far my experience using Hadoop and HBase, Hadoop/HBase provides API like (TableMapReduceUtil.initTableMApperJob)for computing on the HBase scanned/filtered data. In a user view, it is very straight forward. As ignite already been a SQL grid and compute Grid, it will be very useful to let Ignite compute on its own data(SQL returned). Maybe ignite already can, but a straight forward API will be very convenient for user. Also if ignite can hide some detail technology like affinity and handle them automatically, it will be great. Thanks Shawn
