# RFA appender. Please refer to the log4j.properties file to see more details on this appender.
|
|
# In case one needs to do log rolling on a date change, one should set the environment property
|

# HBASE_ROOT_LOGGER to "<DESIRED_LOG LEVEL>,DRFA".
|
|
# For example:
|
|
# HBASE_ROOT_LOGGER=INFO,DRFA
|
|
# The reason for changing default to RFA is to avoid the boundary case of filling out disk space as
|
|
# DRFA doesn't put any cap on the log size. Please refer to HBase-5655 for more context.
