Hi  , we started our tests on cluster ( hbase 0.90.1 , hadoop append) ,
   I set  HBASE_HEAPSIZE to 4000m  in hbase-env.sh and got 3 processes which
has heap size 4000m:

my questions are:
  1)What is the way to set separately heap size for these processes. In case
I want to give to zookeper less heap size what is the properties should I
use?
  2)Assuming  that I want to set 4000m for hbase,  Does it mean that all
these 3 processes  have to have 4000m heap size? What is the advisable heap
size for hbase?

*the processes are: *

Thank you St.Ack
   the question is regarding setting heap size for hbase:

 As I understand there are 3 processes HBASE master , Hbase Region server ,
Zookeper.
What is the heap size should I set for these processes? I don't remember
where do I see 4000m was recommended , but does it mean that all 3 processes
have to have 4000m?

Oleg:
Instead of setting the heap size using the common HBASE_HEAP_SIZE, use
the process specific OPTS to set it.

As Stack says, for instance to set zookeeper specific heap size, you
can uncomment and set the heap size
export HBASE_ZOOKEEPER_OPTS="-Xmx1000m $HBASE_JMX_BASE
-Dcom.sun.management.jmxremote.port=10104"

and so forth instead of HBASE_HEAP_SIZE.

Perhaps you saw this in
http://www.slideshare.net/schubertzhang/hbase-0200-performance-evaluation?

ZooKeeper is managed external of HBase in production. It should not
really require a ~4G heap space.

RegionServer should need all the extra RAM it can get, if am right, so
set it for those surely (more than 4 is good too, if available).

Hi,

I was wondering how much folks typical give to hbase and how much they
leave for the file system cache for the region server. I am using hbase
0.94 and running only the region server and data node daemons. I have a
system with 15G ram.

Thanks
