Ray Chiang created YARN-2159:
--------------------------------
Summary: allocateContainer() in SchedulerNode needs a clearer
LOG.info message
Key: YARN-2159
URL: https://issues.apache.org/jira/browse/YARN-2159
Project: Hadoop YARN
Issue Type: Improvement
Components: resourcemanager
Reporter: Ray Chiang
Assignee: Ray Chiang
Priority: Minor
This bit of code:
LOG.info("Assigned container " + container.getId() + " of capacity "
+ container.getResource() + " on host " + rmNode.getNodeAddress()
+ ", which currently has " + numContainers + " containers, "
+ getUsedResource() + " used and " + getAvailableResource()
+ " available");
results in a line like:
2014-05-30 16:17:43,573 INFO
org.apache.hadoop.yarn.server.resourcemanager.scheduler.fair.FSSchedulerNode:
Assigned container container_1400666605555_0009_01_001111 of capacity
<memory:1536, vCores:1> on host machine.host.domain.com:8041, which currently
has 18 containers, <memory:27648, vCores:18> used and <memory:3072, vCores:0>
available
That message is fine in most cases, but looks pretty bad after the last
available allocation, since it says something like "vCores:0 available".
Perhaps one of the following phrasings is better?
- "which has 18 containers, <memory:27648, vCores:18> used and <memory:3072,
vCores:0> available after allocation"
