Subject [jira] Commented: (PIG-166) Disk Full
Date Tue, 25 Mar 2008 13:19:26 GMT

    [ https://issues.apache.org/jira/browse/PIG-166?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12581926#action_12581926

Pi Song commented on PIG-166:
-----------------------------

Also relating to bag spilling problem that we usually have a lot of small bags (too many small
files=slow on most filesystems), I'm thinking about having the file manager managing packing
of small files into big files for better performance.

> 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.
