项目场景：
- 操作系统：Ubuntu 18- Hadoop版本：Hadoop 3.1.3
- HBase版本：2.2.2
- JDK版本：1.8
- Java IDE：eclipse
问题描述：
进入shell界面时蹦出好多信息：
提示：/usr/local/hadoop/bin/…/libexec/hadoop-functions.sh: line 2395: HADOOP_ORG.APACHE.HADOOP.HBASE.UTIL.GETJAVAPROPERTY_USER: bad substitution
/usr/local/hadoop/bin/…/libexec/hadoop-functions.sh: line 2360: HADOOP_ORG.APACHE.HADOOP.HBASE.UTIL.GETJAVAPROPERTY_USER: bad substitution
/usr/local/hadoop/bin/…/libexec/hadoop-functions.sh: line 2455: HADOOP_ORG.APACHE.HADOOP.HBASE.UTIL.GETJAVAPROPERTY_OPTS: bad substitution
SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in [jar:file:/usr/local/hadoop/share/hadoop/common/lib/slf4j-log4j12-1.7.25.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: Found binding in [jar:file:/usr/local/hbase/lib/client-facing-thirdparty/slf4j-log4j12-1.7.25.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an explanation.
SLF4J: Actual binding is of type [org.slf4j.impl.Log4jLoggerFactory]
HBase Shell
原因分析：
中文显示：无效变量名，错误：找不到或无法加载主类 可能是Hadoop和Hbase包冲突所致
解决方案：
进入/usr/local/hbase/conf/hbase-env文件，将最后一行不允许注释
原来
取消注释，保存退出
重新进入shell界面，问题解决了
