--------------------------------------------
Summary: Range support when serving a container log
Key: YARN-6002
URL: https://issues.apache.org/jira/browse/YARN-6002
Project: Hadoop YARN
Issue Type: Bug
Components: nodemanager
Reporter: Raul Gutierrez Segales
Priority: Minor
Currently, when we access a container's logfile (via
/ws/v1/node/containerlogs/) we can only get the full content, not a specified
range.
Support for the Range: header would improve this, special when dealing with big
files that need to be tailed or streamed, i.e.:
{code}
curl -H 'Range: bytes=10240' \
http://node:8042/ws/v1/node/containerlogs/container_XXX/stdout
{code}
