Thai,
Why are you not using the slf4j jars inside ACCUMULO_HOME/lib?
Can you successfully run these commands:
jar tf /usr/local/Cellar/accumulo/1.7.0/lib/slf4j-api.jar
jar tf /usr/local/Cellar/accumulo/1.7.0/lib/slf4j-log4j12.jar

Hi Josh and Sean,
Thanks for your reply. I already made the verifications several times.
Below is the information you asked:
1. I got Accumulo from Apache. The version is 1.7.0. I did place the
installed accumulo in the same place with Hadoop and Zookeeper for
convenience.
2. I installed Hadoop 2.7 and Zookeeper using homebrew.
3. This is $HADOOP_PREFIX in accumulo-env.sh:
Mac :: accumulo/1.7.0/conf ‹master› » grep HADOOP_PREFIX accumulo-env.sh
test -z "$HADOOP_PREFIX" && export
HADOOP_PREFIX=/usr/local/Cellar/hadoop/2.7.0/libexec
HADOOP_PREFIX="$HADOOP_HOME"
# export
LD_LIBRARY_PATH=${HADOOP_PREFIX}/lib/native/${PLATFORM}:${LD_LIBRARY_PATH}
Mac :: accumulo/1.7.0/conf ‹master› »
4. This is $HADOOP_PREFIX and $ACCUMULO_HOME in my environment:
Mac :: accumulo/1.7.0/conf ‹master› » echo $HADOOP_PREFIX
/usr/local/Cellar/hadoop/2.7.0/libexec
Mac :: accumulo/1.7.0/conf ‹master› » echo $ACCUMULO_HOME
/usr/local/Cellar/accumulo/1.7.0
Mac :: accumulo/1.7.0/conf ‹master› »
5. At first, I ran $ACCUMULO_HOME/bin/accumulo init but got the errors
as I said in the very first post. I then slightly modified the script
$ACCUMULO_HOME/bin/accumulo like this:
XML_FILES="${ACCUMULO_CONF_DIR}"
#LOG4J_JAR=$(find -H "${HADOOP_PREFIX}/lib"
"${HADOOP_PREFIX}"/share/hadoop/common/lib -name 'log4j*.jar' -print
2>/dev/null | head -1)
#LOG4J_JAR=$(find -H "${HADOOP_PREFIX}"/share/hadoop/common/lib -name
'log4j*.jar' -print 2>/dev/null | head -1)
LOG4J_JAR=/usr/local/Cellar/hadoop/2.7.0/libexec/share/hadoop/common/log4j-1.2.17.jar
#SLF4J_JARS="${ACCUMULO_HOME}/lib/slf4j-api.jar:${ACCUMULO_HOME}/lib/slf4j-log4j12.jar"
SLF4J_JARS="${HADOOP_PREFIX}/share/hadoop/common/lib/slf4j-api-1.7.10.jar:${HADOOP_PREFIX}/share/hadoop/common/lib/slf4j-log4j12-1.7.10.jar"
#SLF4J_JARS=/usr/local/Cellar/accumulo/1.7.0/lib/slf4j-api.jar:/usr/local/Cellar/accumulo/1.7.0/lib/slf4j-log4j12.jar
CLASSPATH="${XML_FILES}:${START_JAR}:${SLF4J_JARS}:${LOG4J_JAR}:${CLASSPATH}"
echo "Classpath ..."
echo ${CLASSPATH}
Let me know if you need any other information.
Thanks,
Thai

Accumulo 1.7.0 should have the necessary slf4j jars in
ACCUMULO_HOME/lib. The log4j jar should be pulled automatically
from your Hadoop distribution.
Are you using some vendor's version of Hadoop or did you get it
from Apache (and what version is it)?
Can you please verify the values for HADOOP_PREFIX in
accumulo-env.sh? Can you also make sure that you don't have any
incorrect values for HADOOP_PREFIX or ACCUMULO_HOME in your
current environment (check `env`)?
