[jira] [Created] (HADOOP-16782) Loading jdwp with
HADOOP_CLIENT_OPTS throws an error
Deep created HADOOP-16782:
-----------------------------
Summary: Loading jdwp with HADOOP_CLIENT_OPTS throws an error
Key: HADOOP-16782
URL: https://issues.apache.org/jira/browse/HADOOP-16782
Project: Hadoop Common
Issue Type: Bug
Components: scripts
Affects Versions: 3.2.0
Environment: OS: Ubuntu 18.04.3 LTS
Reporter: Deep
I'm trying to debug 'distcp' by setting any of the following options:
export HADOOP_CLIENT_OPTS="-Xdebug -Xrunjdwp:transport=dt_socket,address=5012,server=y,suspend=n"
export MAPRED_DISTCP_OPTS="-Xdebug -Xrunjdwp:transport=dt_socket,address=5012,server=y,suspend=n"
When I attempt to load jdwp with HADOOP_CLIENT_OPTS, 'NAMENODES' variable in 'start-dfs.sh' is incorrectly set to this value: "Listening for transport dt_socket at address: 5012 localhost".
When I attempt to load jdwp with MAPRED_DISTCP_OPTS, it is not even read by 'start-dfs.sh'
I followed the instructions specified here:
[https://hadoop.apache.org/docs/r3.2.0/hadoop-project-dist/hadoop-common/UnixShellGuide.html]
Goal is to debug 'distcp' so if there is an alternative way, that works as well.
