Subject [jira] Commented: (PIG-166) Disk Full
Date Tue, 01 Apr 2008 16:32:24 GMT

    [ https://issues.apache.org/jira/browse/PIG-166?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12584207#action_12584207

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

Pi,

At this point I think we are bound by CPU rather than disk writes (especially as we do local
writes) but over time that might change. Also, I think we could get fairly high compression
rate and save significant amount of space. So I do agree that we need to look into this.

> 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.
