[jira] [Updated] (HADOOP-7086) Retrying socket connection failure
times can be made as configurable
[ https://issues.apache.org/jira/browse/HADOOP-7086?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Devaraj K updated HADOOP-7086:
------------------------------
Resolution: Duplicate
Release Note: (was: Added a property 'ipc.client.connect.max.socket.retries' to configure the socket retries when the Socket Exception is thrown. If we don't configure this property, it will take the default value as 45.)
Status: Resolved (was: Patch Available)

> Retrying socket connection failure times are hard coded as 45 and it is giving the retryring message for 45 times as below.
> 2011-01-04 15:14:30,700 INFO ipc.Client (Client.java:handleConnectionFailure(487)) - Retrying connect to server: /10.18.52.124:50020. Already tried 1 time(s).
> This can be made as configurable and also we can keep the default value as 45. If the user wants to decrease/increase, they can add this configurable property otherwise it can continue with the default value.
