---------------------------------
Summary: Print more detail on Ratis send request ERROR
Key: HDDS-11760
URL: https://issues.apache.org/jira/browse/HDDS-11760
Project: Apache Ozone
Issue Type: Task
Reporter: Siyao Meng
Assignee: Siyao Meng
Currently Ozone client doesn't give any detail on Ratis send request failure
with default logging level:
{code:java}

It should print at least why it failed when it ERRORed out. Only when DEBUG
logging is enabled will it print the stacktrace. e.g. in the case above it
leads to HDDS-11257:
{code:java}
Caused by: java.lang.NoClassDefFoundError:
org/apache/ratis/thirdparty/io/netty/handler/proxy/HttpProxyHandler {code}
This prevents us devs from debugging the issue efficiently. I will make a
change in Ozone/Ratis client to print the details / stacktrace when ERROR has
occurred.
