Subject [jira] [Commented] (HDFS-4301) 2NN image transfer timeout problematic
Date Fri, 28 Dec 2012 09:24:12 GMT

    [ https://issues.apache.org/jira/browse/HDFS-4301?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13540405#comment-13540405

liang xie commented on HDFS-4301:
---------------------------------

[~tlipcon], IMHO the current implement seems OK,  we can enlarge DFS_IMAGE_TRANSFER_RATE_KEY
&& DFS_IMAGE_TRANSFER_TIMEOUT_KEY to relieve, right ?
or if you have better idea, could you shed some light on it,  thanks in advance.

> HDFS-1490 added a timeout on image transfer. But, it seems like the timeout is actually
applying to the entirety of the image transfer operation. So, if the image or edits are large
(multiple GB) or the transfer is heavily throttled, it is likely to time out repeatedly.
