------------------------------------------
Summary: LLAP: DefaultMetricsSystem.shutdown() should not be
called in TezChild
Key: TEZ-2171
URL: https://issues.apache.org/jira/browse/TEZ-2171
Project: Apache Tez
Issue Type: Bug
Affects Versions: 0.7.0
Reporter: Prasanth Jayachandran
DefaultMetricsSystem.shutdown() is called in TezChild. IIUC, shutdown is meant
to be called in daemon context (datanode/namenode). LLAP daemon initializes the
metrics system, after running the first query TezChild shuts down the metrics
system which results in closing of all metrics endpoints/sinks.
