Akira AJISAKA updated HADOOP-7984:
----------------------------------
Description: It would be helpful if bin/hadoop had --loglevel option
to change the log level. Currently users need to set an env variable or prefix
the command (eg "HADOOP_ROOT_LOGGER=DEBUG,console hadoop distcp") which isn't
very user friendly. (was: It would be helpful if bin/hadoop had verbose and
debug flags. Currently users need to set an env variable or prefix the command
(eg "HADOOP_ROOT_LOGGER=DEBUG,console hadoop distcp") which isn't very user
friendly. We currently log INFO by default. How about we only log ERROR and
WARN by default, then -verbose triggers INFO and -debug triggers DEBUG?)
Target Version/s: 3.0.0, 2.6.0 (was: 2.0.0-alpha, 3.0.0)
Summary: Add hadoop --loglevel option to change log level (was:
Add hadoop command verbose and debug options)
Hadoop Flags: (was: Incompatible change)
Updated the description. I'll file a separate jira to change the default log
level.
