Jagadish created YARN-6078:
------------------------------
Summary: Containers stuck in Localizing state
Key: YARN-6078
URL: https://issues.apache.org/jira/browse/YARN-6078
Project: Hadoop YARN
Issue Type: Bug
Reporter: Jagadish
I encountered an interesting issue in one of our Yarn clusters (where the
containers are stuck in localizing phase).
Our AM requests a container, and starts a process using the NMClient.
According to the NM the container is in LOCALIZING state:
{code}
1. 2017-01-09 22:06:18,362 [INFO] [AsyncDispatcher event handler]
container.ContainerImpl.handle(ContainerImpl.java:1135) - Container

/../..//.nmPrivate/container_e03_1481261762048_0541_02_000060.tokens.

According to the RM the container is in RUNNING state:
{code}
2017-01-09 22:06:17,110 [INFO] [IPC Server handler 19 on 8030]
rmcontainer.RMContainerImpl.handle(RMContainerImpl.java:410) -
container_e03_1481261762048_0541_02_000060 Container Transitioned from
ALLOCATED to ACQUIRED

rmcontainer.RMContainerImpl.handle(RMContainerImpl.java:410) -
container_e03_1481261762048_0541_02_000060 Container Transitioned from ACQUIRED
to RUNNING
{code}
When I click the Yarn RM UI to view the logs for the container, I get an error
that
{code}
No logs were found. state is LOCALIZING
{code}
The Node manager 's stack trace seems to indicate that the NM's LocalizerRunner
is stuck waiting to read from the sub-process's outputstream.

I did a {code}ps aux{code} and confirmed that there was no container-executor
process running with INITIALIZE_CONTAINER that the localizer starts. It seems
that the output stream pipe of the process is still not closed (even though the
localizer process is no longer present).
