[jira] [Commented] (FLUME-2130) Handle larger payloads via SyslogUDPSource

["Hari Shreedharan (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/FLUME-2130?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13894984#comment-13894984 ] 

Hari Shreedharan commented on FLUME-2130:
-----------------------------------------

This looks good. The only issue is that UDP packets can't be fragmented, so even "large" packets may not reach the source at all based on the MTU of the netwrok being used. For example, I modified this patch's test and it was fine until I went up slightly about 7K (using the test in the patch itself).
