Szilard Nemeth commented on YARN-9008:
--------------------------------------
Thanks [~pbacsko] for uploading this patch!
In {{AppMaster.java}}:
1. The code block where you iterate over {{localizableFiles}}:
I would call \{{suffix}} differently, for example: filePath, or something like
that.
2. Also in the same added code block, I don't get why the variable
\{{scFileStatus}} is named like that. What is *sc* in this context? Can you
please change it to a more descriptive name?
In Client.java:
1. Nit: Remove the additional blank commented line between the two sentences in
the comments above:
{\{ StringBuilder localizableFiles = new StringBuilder(); }}
2. In {{uploadFile}}: I would call suffix differently, as indicated above.
Testing:
In {{Client.java}}, you added a code block that iterates over the localizable
files and uploads them.
Can you somehow test if this code works correctly? I mean some test that runs
the client and checks if uploadFile invokes \{{FileSystem}} with the correct
arguments?
Thanks!

> YARN distributed shell is a very handy tool to test various features of YARN.
> However, it lacks support for file localization - that is, you define files
> in the command line that you wish to be localized remotely. This can be
> extremely useful in certain scenarios.
