Jianfei Jiang created HDFS-13401:
------------------------------------
Summary: Different behavior in mkdir when the target folder of
mount table is uncreated
Key: HDFS-13401
URL: https://issues.apache.org/jira/browse/HDFS-13401
Project: Hadoop HDFS
Issue Type: Bug
Reporter: Jianfei Jiang
Assignee: Jianfei Jiang
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.
