Subject [jira] [Created] (HBASE-9881) enabling HBASE_ROOT_LOGGER in hbase-env.sh would suppress the hbase console output
Date Mon, 04 Nov 2013 08:48:18 GMT
takeshi.miao created HBASE-9881:
-----------------------------------

             Summary: enabling HBASE_ROOT_LOGGER in hbase-env.sh would suppress the hbase
console output
                 Key: HBASE-9881
                 URL: https://issues.apache.org/jira/browse/HBASE-9881
             Project: HBase
          Issue Type: Bug
    Affects Versions: 0.96.0
            Reporter: takeshi.miao
            Priority: Trivial


Currently, there seems two call paths to determine the value of _hbase.root.logger_ in log4j.properties
file.

1. hbase -> hbase-config.sh -> hbase-env.sh (set _HBASE_ROOT_LOGGER_ if any) -> hbase
(set default value to HBASE_ROOT_LOGGER if no variable declared)

2. hbase-daemon.sh -> hbase-config.sh -> hbase-env.sh (set _HBASE_ROOT_LOGGER_ if any)
-> hbase-daemon.sh (set default value to HBASE_ROOT_LOGGER if no variable declared)

We found an issue at call path#1, while using 'bin/hbase' the original +console output will
redirect to the log file+ if the _HBASE_ROOT_LOGGER_ enabled in hbase-env.sh

for example
1. we use 'bin/hbase zkcli' to connect to zookeeper, will see following log output to the
console...
{noformat}
# bin/hbase zkcli

WATCHER::

2. then we enable the _HBASE_ROOT_LOGGER_ in hbase-env.sh
{noformat}
129 # HBASE_ROOT_LOGGER=INFO,DRFA
{noformat}
remove pound sign to enable the _HBASE_ROOT_LOGGER_
{noformat}
129 HBASE_ROOT_LOGGER=INFO,DRFA
{noformat}

3. and re-issue the 'bin/hbase zkcli' again, we will see the logging msg disappear in console
output
{noformat}

WATCHER::

[zk: scottm-hbase-1.lab:2181(CONNECTED) 0]
{noformat}

The reason is that the _HBASE_ROOT_LOGGER_ in hbase-env.sh over-writes the _HBASE_ROOT_LOGGER_
in hbase shell file

put the _egrep_ results for _HBASE_ROOT_LOGGER_ for reference.
{code:shell}
$ egrep -in --color "HBASE_[a-zA-Z]+_LOGGER" conf/*
conf/hbase-env.sh:127:# HBASE_ROOT_LOGGER to "<DESIRED_LOG LEVEL>,DRFA".
conf/hbase-env.sh:129:# HBASE_ROOT_LOGGER=INFO,DRFA

$ egrep -in --color "HBASE_[a-zA-Z]+_LOGGER" bin/*
bin/hbase:47:#   HBASE_ROOT_LOGGER The root appender. Default is INFO,console
bin/hbase:345:HBASE_OPTS="$HBASE_OPTS -Dhbase.root.logger=${HBASE_ROOT_LOGGER:-INFO,console}"

bin/hbase:355:  HBASE_OPTS="$HBASE_OPTS -Dhbase.security.logger=${HBASE_SECURITY_LOGGER:-INFO,NullAppender}"
…
bin/hbase-daemon.sh:147:export HBASE_ROOT_LOGGER=${HBASE_ROOT_LOGGER:-"INFO,RFA"}
bin/hbase-daemon.sh:148:export HBASE_SECURITY_LOGGER=${HBASE_SECURITY_LOGGER:-"INFO,RFAS"}
