Meaning of backup task
Renata Ghisloti Duarte de... 2013-04-03, 19:31
Hey guys, sometimes I get an undesired output when running Hive unit
tests. It happens on Hive query "plans", for example:

[junit] diff -a
-b /home/hive-0.10/release-0.10.0/build/ql/test/logs/positive/groupby1.q.xml /home/hive-0.10/release-0.10.0/ql/src/test/results/compiler/plan/groupby1.q.xml
    [junit] 4d3
    [junit] <   <void property="backupChildrenTasks"/>

Is this backup task the same that is created on Join operations? That
is, when the JVM memory is not enough, and a backup local task is
created?

Thanks in advance,
Renata.
