Building failure with Hadoop 3.3.1

[jerrychenhf]

When building with the following command:
mvn clean package -Pdist -Dhadoop.plat.version=3.3.1 -Dhadoop.version=3.3.1 -Dmaven.test.skip=true

The build failures.

1. First the duplicated class error for OBSClientFactory. There are two java files (OBSClientFactory.java and ObsClientFactory.java) which have the definition of the same interface.
2. When delelete ObsClientFactory.java and the compile goes on but a few compiling errors for StringUtils and other functions from commons. Seems that the jar is not available using hadoop 3.3.1 dependency. Hadoop 3.1.1 is correct.

It is very strange why there is an issue like duplicate class error since the project is releasing.

The thing for fix and compile:

1. rm hadoop-huaweicloud/src/main/java/org/apache/hadoop/fs/obs/ObsClientFactory.java
2. Replace apache.commons.lang import with apache.commons.lang3 because Hadoop 3.3.1 is depending commons.lang3 instead of commons.lang.
   sed -i "s/apache.commons.lang/apache.commons.lang3/g" grep "apache.commons.lang" -rl ./

Hi @aheartfulguy, could you help to address this issue? When @jerrychenhf and I trying to add Huawei Cloud support into CloudTik, we face it, thanks.
