-----------------------------------
Summary: Differentiate log messages by service instance in test
output
Key: HDDS-1427
URL: https://issues.apache.org/jira/browse/HDDS-1427
Project: Hadoop Distributed Data Store
Issue Type: Improvement
Components: test
Reporter: Arpit Agarwal
When running tests, the log output from multiple services is interleaved. This
makes it very hard to follow the sequence of events.
This is especially seen with MiniOzoneChaosCluster which starts 20 DataNodes in
the same process.
One way we can do this is by using [Log4j
NDC|https://logging.apache.org/log4j/1.2/apidocs/org/apache/log4j/NDC.html] or
[slf4j|https://www.slf4j.org/api/org/slf4j/MDC.html] to print the PID and
thread name/thread ID. It probably won't be a simple change.
