[jira] [Updated] (YARN-2159) allocateContainer() in SchedulerNode
needs a clearer LOG.info message
[ https://issues.apache.org/jira/browse/YARN-2159?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Ray Chiang updated YARN-2159:
-----------------------------
Description:
This bit of code:
{quote}
LOG.info("Assigned container " + container.getId() + " of capacity "
+ container.getResource() + " on host " + rmNode.getNodeAddress()
+ ", which currently has " + numContainers + " containers, "
+ getUsedResource() + " used and " + getAvailableResource()
+ " available");
{quote}
results in a line like:
{quote}
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
{quote}
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"
