Subject [jira] Commented: (PIG-166) Disk Full
Date Mon, 31 Mar 2008 16:46:24 GMT

    [ https://issues.apache.org/jira/browse/PIG-166?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12583742#action_12583742

Olga Natkovich commented on PIG-166:
------------------------------------

Couple of comments:

(1) We need to validate that we are spilling correctly, like not spilling the same data multiple
times
(2) If this is legitimate data, we need to look at compressing it

> Occasionally spilling fills up (all) hard drive(s) on a Data Node and crashes Task Tracker
(and other processes) on that node. We need to have a safety net and fail the task before
crashing happens (and more). 
> In Pig + Hadoop setting, Task Trackers get Black Listed. And Pig console gets stock at
a percentage without returning nodes to cluster. I talked to Hadoop team to explore Max Percentage
idea. Nodes running into this problem get into permanent problems and manual cleaning by administrator
is necessary.
