[jira] [Created] (HADOOP-8616) ViewFS configuration requires a
trailing slash
Eli Collins created HADOOP-8616:
-----------------------------------
Summary: ViewFS configuration requires a trailing slash
Key: HADOOP-8616
URL: https://issues.apache.org/jira/browse/HADOOP-8616
Project: Hadoop Common
Issue Type: Bug
Components: viewfs
Affects Versions: 2.0.0-alpha, 0.23.0
Reporter: Eli Collins
If the viewfs config doesn't have a trailing slash commands like the following fail:
{noformat}
bash-3.2$ hadoop fs -ls
-ls: Can not create a Path from an empty string
Usage: hadoop fs [generic options] -ls [-d] [-h] [-R] [<path> ...]
{noformat}
We hit this problem with the following configuration because "hdfs://ha-nn-uri" does not have a trailing "/".
{noformat}
<property>
<name>fs.viewfs.mounttable.foo.link./nameservices/ha-nn-uri</name>
<value>hdfs://ha-nn-uri</value>
</property>
{noformat}

Aaron T. Myers updated HADOOP-8616:
-----------------------------------
Attachment: HADOOP-8616.patch
Right after I initially committed the patch, I realized that the new test file was missing the Apache license header. Here's an updated patch which just adds that missing license.
I've reverted my initial commit, and am going to commit this updated patch now, since it differs only in the comment.

Sandy Ryza commented on HADOOP-8616:
------------------------------------
The problem occurs when the ViewFileSystem attempts to create a ChRootedFileSystem as its target file system. It calls getPath() on the URI object passed to it, which, for a URI like "hdfs://ha-nn-uri", returns an empty string. Where does it make the most sense to handle this? Where the ViewFileSystem reads the config (in the InodeTree constructor)? Where the ViewFileSystem creates the URI (inside the createLink() method in InodeTree)? In the ChRootedFileSystem constructor?

Aaron T. Myers commented on HADOOP-8616:
----------------------------------------
The patch looks pretty good to me. Two little comments:
# I'd recommend using {{String#isEmpty()}} instead of {{String#length() == 0}}.
# Does a similar change not need to be made to the FileContext side of the house, i.e. ChRootedFs?

Sandy Ryza commented on HADOOP-8616:
------------------------------------
The ChRootedFs constructor takes a Path, not a URI, like the ChRootedFileSystem. The same problem could occur if ViewFs were passed a URI without a trailing slash, but this would have to be handled in ViewFs.

Daryn Sharp commented on HADOOP-8616:
-------------------------------------
Based on my understanding, I'd saying {{ChRootedFileSystem}} is the best place for the fix. Anywhere else would be working around its bug. The handling of the chroot path has always been a bit complex so maybe this is a good time to simplify it.

> If the viewfs config doesn't have a trailing slash commands like the following fail:
> {noformat}
> bash-3.2$ hadoop fs -ls
> -ls: Can not create a Path from an empty string
> Usage: hadoop fs [generic options] -ls [-d] [-h] [-R] [<path> ...]
> {noformat}
> We hit this problem with the following configuration because "hdfs://ha-nn-uri" does not have a trailing "/".
> {noformat}
> <property>
> <name>fs.viewfs.mounttable.foo.link./nameservices/ha-nn-uri</name>
> <value>hdfs://ha-nn-uri</value>
> </property>
> {noformat}
