Enis Soztutar commented on HBASE-11936:
---------------------------------------

Yeah, Anoop is right. I did a test for this in HBASE-10841, however I was not able to get the proper return values for override methods from the subclasses. We should override the method in both Scan and Get, and cast the appropriate return type. 

{code}
public Scan setIsolationLevel() {
   return (Scan)super.setIsolationLevel();
}
{code}

> The Get operation is implemented in HBase as a Scan. The default isolation level for Scan is READ_COMMITTED. The API to change the isolation level is part of Scan class and there is no way for Get operation to change this from default. We should move this API up to Query (which is a parent of both: Scan and Get).
