cannot find symbol [ERROR] symbol: class DistributedFileSystem

編譯tez時，由於使用的是hadoop3.1.2

所以出現以下錯誤，

[ERROR] COMPILATION ERROR : 
[INFO] -------------------------------------------------------------
[ERROR] /home/appleyuchi/bigdata/apache-tez-0.9.2-src/tez-api/src/test/java/org/apache/tez/client/TestTezClientUtils.java:[48,30] cannot find symbol
  symbol:   class DistributedFileSystem
  location: package org.apache.hadoop.hdfs
[ERROR] /home/appleyuchi/bigdata/apache-tez-0.9.2-src/tez-api/src/test/java/org/apache/tez/client/TestTezClientUtils.java:[680,50] cannot find symbol

  location: class org.apache.tez.client.TestTezClientUtils
[ERROR] /home/appleyuchi/bigdata/apache-tez-0.9.2-src/tez-api/src/test/java/org/apache/tez/common/TestTezCommonUtils.java:[62,42] incompatible types: org.apache.hadoop.hdfs.DistributedFileSystem cannot be converted to org.apache.hadoop.fs.FileSystem

解決方案是:

 mvn install                           -Dhadoop.version=3.1.2 -DskipTests -Dmaven.javadoc.skip=true

改成

mvn install -Phadoop28 -Dhadoop.version=3.1.2 -DskipTests -Dmaven.javadoc.skip=true
