Summary: Bug at ListNodes In ChefContext
Key: JCLOUDS-624
URL: https://issues.apache.org/jira/browse/JCLOUDS-624
Project: jclouds
Issue Type: Bug
Components: jclouds-chef
Affects Versions: 1.8.0
Reporter: Luciano Sabença
Hi.
I've found a bug when using ListNodes in jclouds-chef. The problem is related
to the thread pool that is used when ListNodes is called.
When using ListNodes, for each node that exists in Chef, a new task is
submitted to the pool "USER_THREADS". Each one of these submitted tasks
generates another Runnable - to do the HTTP request - and submits it to the
same thread pool. So, when we have a large number of nodes(an usual scenario
when dealing with Chef), all threads in the pool are blocked waiting its own
thread responsible to do the HTTP request and no thread is left to effectively
do the HTTP request. After the configured timeout, a lot of
java.util.concurrent.TimeoutException are thrown.
I am already working to fix it and I will release a pull request soon (maybe,
in a few days).
Thanks
