Potential infinite loop in updateMinSlots
-----------------------------------------
Key: HADOOP-5075
URL: https://issues.apache.org/jira/browse/HADOOP-5075
Project: Hadoop Core
Issue Type: Bug
Components: contrib/fair-share
Reporter: Matei Zaharia
Priority: Blocker
Attachments: hadoop-5075.patch
We ran into a problem at Facebook where the updateMinSlots loop in the
scheduler was repeating infinitely. This might happen if, due to rounding, we
are unable to assign the last few slots in a pool. This patch adds a break
statement to ensure that the loop exists if it hasn't managed to assign any
slots.
