本文解决在配置Hadoop和HBase时遇到的问题，特别是当出现警告信息提示HBase和HCatalog安装路径不存在，以及错误信息提示HBase jar包未在类路径中时。通过将sqoop-1.4.4.jar文件复制到hadoop的lib目录下，可以解决类加载问题。同时，提供了解决$HBASE_HOME和$HCAT_HOME环境变量配置的指导。

错误: 找不到或无法加载主类 org.apache.sqoop.Sqoop
最终解决办法是吧sqoop目录下的sqoop-1.4.4.jar拷贝到hadoop的lib目录下解决

Warning: /usr/lib/hbase does not exist! HBase imports will fail.
Please set $HBASE_HOME to the root of your HBase installation.
Warning: /usr/lib/hcatalog does not exist! HCatalog jobs will fail.
Please set $HCAT_HOME to the root of your HCatalog installation.
Warning: $HADOOP_HOME is deprecated.

bin/configure-sqoop文件中把以下内容注释掉就可以了
## Moved to be a runtime check in sqoop.
#if [ ! -d "${HBASE_HOME}" ]; then
#  echo "Warning: $HBASE_HOME does not exist! HBase imports will fail."
#  echo 'Please set $HBASE_HOME to the root of your HBase installation.'
#fi

## Moved to be a runtime check in sqoop.
#if [ ! -d "${HCAT_HOME}" ]; then
# echo "Warning: $HCAT_HOME does not exist! HCatalog jobs will fail."
#  echo 'Please set $HCAT_HOME to the root of your HCatalog installation.'
#fi

ERROR tool.ImportTool: Error during import: HBase jars are not present in classpath, cannot import to HBase!
