HBase 0.92 warnings about SLF4J bindings
Hi all,
I installed HBase 0.92 on Hadoop 1.0.0 and it works okey, but some warning boring me. How to solve it?
.......
hbase(main):001:0> status
SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in [jar:file:/opt/hbase-0.92.0/lib/slf4j-log4j12-1.5.8.jar!/org/slf4j/impl/StaticLoggerBinder.class]

first of all clear hdfs folder which you created while installing hadoop... its
the same folder which contains zoopkeeper files.
and then delete the file " slf4j-log4j12-1.5.8.jar "
If you dont want to delete then simple move it outside the hbase folder to some
other place.
/home/ahuja/hbase/lib contains slf4j-log4j12-1.5.8.jar
format namenode and then START hbase.
then after running the shell , list all tables and it is should work fine.
Cheers,
Kavish

How have you set your CLASSPATH? You have hadoop on the hbase
CLASSPATH? Try removing one of the slf4js.
