Concurrent Put in Hbase

Lets say I have two Spark Jobs that inserts data to HBase. Is it okay if I have two concurrent jobs inserting to the same table at the same time?

That would be absolutely no problem. It is exactly what Hbase was designed for; handling many, many concurrent insert (put) and retrieve (get) requests. So it will handle two or more concurrent jobs, even if they handle the same keys.

Not really, if you have a couple of Regionservers and the key space is distributed evenly. Once again this is the sweetspot of HBase, high volume random read/write workloads.
