    • Type: Bug
    • Status: Open
    • Priority: Major
    • Resolution: Unresolved
    • Affects Version/s: 3.0.1
    • Fix Version/s: None
    • Component/s: federation, hdfs
    • Labels:
      None

      Description

      In federation cases, if we have a config like below:

      <property>
      <name>fs.viewfs.mounttable.ClusterX.link./foo</name>
      <value>hdfs://nn2-clusterx.example.com:8020/footarget</value>
      </property>

      When the folder hdfs://nn2-clusterx.example.com:8020/projects/footarget is not actually exist, the command hdfs dfs ls / can still see the folder, but the folder is not actually exist. then we try to use mkdir command to create the viewfs folder hdfs dfs mkdir /foo, the return code is true, but the folder is not created. However, when we use hdfs dfs mkdir -p /foo/xxx which have a deeper location to create folder, the folder is successfully created. The results in these two cases may be ambigiuous.
