I am new to Hbase. I have installed it and while running hbase commands I get the following error;

SLF4J: Class path contains multiple SLF4J bindings.

SLF4J: Found binding in [jar:file:/home/hduser/hbase-0.98.5-hadoop2/lib/slf4j-log4j12-1.6.4.jar!/org/slf4j/impl/StaticLoggerBinder.class]

SLF4J: Found binding in [jar:file:/home/hduser/hadoop/lib/slf4j-log4j12-1.4.3.jar!/org/slf4j/impl/StaticLoggerBinder.class]

SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an explanation. ERROR: Could not initialize class org.apache.hadoop.security.JniBasedUnixGroupsMapping

Here is some help for this command: List all tables in hbase. Optional regular expression parameter could be used to filter the output.

Could anyone help?
