Longping Jie updated HBASE-28759:
---------------------------------
Description:
SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in
[jar:file:/data/app/hadoop-3.3.6/share/hadoop/common/lib/slf4j-reload4j-1.7.36.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: Found binding in
[jar:file:/data/app/hbase-2.5.10/lib/client-facing-thirdparty/log4j-slf4j-impl-2.17.2.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: See [http://www.slf4j.org/codes.html#multiple_bindings] for an
explanation.
The above log dependency conflict causes the regionserver to be unable to
output logs after it is started.
By default, in the hbase script file in the bin directory, the value of
HBASE_DISABLE_HADOOP_CLASSPATH_LOOKUP is true, which will append the hadoop lib
to the classpath. In this way, after the hbase process is started, the hadoop
jar will be loaded, which may cause dependency conflicts.
Is it possible to set the variable HBASE_DISABLE_HADOOP_CLASSPATH_LOOKUP in the
hbase-env.sh file, set the default value to true, and only modify this value to
false when necessary?
