Subject [jira] Commented: (HADOOP-6577) IPC server response buffer reset threshold should be configurable
Date Sat, 20 Feb 2010 01:41:28 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-6577?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12836090#action_12836090

Hudson commented on HADOOP-6577:
--------------------------------

Integrated in Hadoop-Common-trunk-Commit #178 (See [http://hudson.zones.apache.org/hudson/job/Hadoop-Common-trunk-Commit/178/])
    . Add hidden configuration option "ipc.server.max.response.size" to change the default
1 MB, the maximum size when large IPC handler response buffer is reset. Contributed by Suresh
Srinivas.

> In HDFS-6460, the response buffers in o.a.h.ipc.Server.Handler was reset when the buffer
grows beyond max size of 1MB. This frees heap from large responses occupying it. This max
response size limit should be configurable. Details in subsequent comment.
