I'm not sure what your point is Bright (Thanks).

[jira] [Commented] (HBASE-4508) Backport HBASE-3777 to 0.90 branch

stack commented on HBASE-4508:
------------------------------
I just tried this patch against the tip of 0.90. On a cluster loaded with regions, I brought down one server, put in place a jar with this patch in place and then brought it back up moving regions back on to the server. A client that was not patched was able to talk to this server. It looks to me like this patch is safe to backport.

Ted Yu updated HBASE-4508:
--------------------------
Release Note:
A new config parameter, hbase.connection.per.config, has been added.
If set to true, there is no connection sharing.
If set to false, connection sharing would be enabled so that fewer connections to zookeeper are used.

TestHCM.testManyNewConnectionsDoesnotOOME did OOME once we introduced hbase.connection.per.config (default true) and before we set it false in that test.

-------------------------------
By compatibility I guess you mean not sharing connections.
hbase.connection.per.config config property has default value of true, keeping the existing behavior in 0.90.4

Ted Yu updated HBASE-4508:
--------------------------
Resolution: Fixed
Release Note:
A new config parameter, hbase.connection.per.config, has been added.
If set to true, there is no connection sharing. This is default setting.
If set to false, connection sharing would be enabled so that fewer connections to zookeeper are used.

That test failing with the default config was a small demonstration of compatibility with prior behavior.

Ted Yu commented on HBASE-4508:
-------------------------------
>From Shrijeet:
1. Rolling restart with 0.90 trunk + patch jar : PASSED
2. Verify that 0.90 trunk jar leaks connection with HTable pool size set to 10 , hbase.zookeeper.property.maxClientCnxns set to 20 and launching 10 client threads : PASSED
3. Verify that 0.90 trunk jar + patch does not leak connection with HTable pool size set to 10 , hbase.zookeeper.property.maxClientCnxns set to 20 and launching 10 client threads : PASSED
4. Verify that 0.90 trunk jar + patch still holds up when HTable pool size set to 10 , hbase.zookeeper.property.
maxClientCnxns set to 5 and launching 100 client threads : PASSED
The established connections in my final test was 2. This I verified using both netstat and zookeeper dump in UI.
One caveat: remember to set hbase.connection.per.config false in order to use connection sharing.
5. hbase.connection.per.config=true , max connections to 300 and bumping ulimit from 1024 to 2048, client threads 100 : PASSED
