YARN-11664. Remove HDFS Binaries/Jars Dependency From Yarn (#6631)
Browse files Browse the repository at this point in the history
To support YARN deployments in clusters without HDFS
some changes have been made in packaging

* new hadoop-common class org.apache.hadoop.fs.HdfsCommonConstants
* hdfs class org.apache.hadoop.hdfs.protocol.datatransfer.IOStreamPair moved
  from hdfs-client to hadoop-common
* YARN handlers for DSQuotaExceededException replaced by use of superclass
  ClusterStorageCapacityExceededException.
