Hi, I have a couple of small issues regarding hadoop/hbase 1. i wanna scan a table, but the table is really huge. so i want the result of the scan to some file so that i can analyze it. how do we go about it???
2. how do you dynamically add and remove nodes in the cluser without disturbing the existing map-reduce jobs (on EC2). 3. suppose my dfs replication is 3. (which implies that i have 3 copies of data in some other location). how do i access other two copies. or how do i find out in which machines are the other copies kept? 4. If my hbase master fails, is there any way i can set another node as my hbase master without disturbing my current map-reduce jobs?? thanks, Raakhi
