Subject [jira] [Commented] (HADOOP-7086) Retrying socket connection failure times can be made as configurable
Date Tue, 31 Jan 2012 16:07:17 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-7086?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13196993#comment-13196993
] 

Devaraj K commented on HADOOP-7086:
-----------------------------------

It is only related to client side, doesn't relate to server. It is not an incompatible change
because it just makes the hardcoded value as configurable and it works same as before this
patch.

> Retrying socket connection failure times are hard coded as 45 and it is giving the retryring
message for 45 times as below.

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.
