Review request for accumulo and Josh Elser.
Bugs: ACCUMULO-2654
https://issues.apache.org/jira/browse/ACCUMULO-2654
Repository: accumulo
Description
-------
Adds a simple utility for creating an empty RFile, leveraging existing code.
Diffs
-----
src/core/src/main/java/org/apache/accumulo/core/file/rfile/CreateEmpty.java PRE-CREATION
src/core/src/main/java/org/apache/accumulo/core/file/rfile/RFileOperations.java 5374332
Diff: https://reviews.apache.org/r/20180/diff/
Testing
-------
tested basic error handling and help messages. tested creating file on hdfs and local file system. tested default codec, gz, and specifying the same codec as default. Used PrintInfo to verify generated files.
Thanks,
Sean Busbey

I believe this an other tests rely on the fact that the test cluster has just been set up and used exclusively for the initial data load. Fixing this assumption will be a fair bit of additional work. Could we do it as a follow on in 1.6+ only?

so a scan of the metadata table for the filename returning something would be sufficient?
FWIW, I cribbed this from another test that uses printinfo to validate locality groups got properly serialized.

thats ok w/ me if the hadoop fs -rm does cause the test to fail when the file does not exist

Thinking about this some more, Accumulo generates unique filenames for every file (even across tables and tablets). So F0000000.rf would only be used if the metadata table had not compacted :) Should probably get the filename from the metadata table.

Turns out the 1.6+ version of these tests already do the lookup.

If this file exist but it not referenced in the metadata table, then this test will not properly validate what its trying to... maybe the test should look in the metadata table to get the filename, or to just verify metadata refs the file

yes, want the test to fail if the file does not exist.... but I am not sure about hadoop return codes, I am also not sure if waitForStop checks return codes....
but this may be moot if the metadata table is scanned to find the filename...

I confirmed that hadoop properly returns non-0 if the file doesn't exist, runOn returns it, and waitForStop checks it.

I'll defer to you to use Precondition here. My concern was only that if user enters "f1.rf f2.rf f3.nrf", it's more user friendly to give error in the beginning rather than aborting with an error in the middle.

Worth switching to Guava's Precondition? core doesn't have a Guava dep in this branch.

We can first validate all args, and then create them in 2nd pass to ensure some files don't get created.

Bingo -- not the end of the world if commons-cli variant doesn't do something. Maybe a log message about the Path that's being created for those cases? Your judgement is sufficient.

I think the help message would be best. If I were using a tool, that'd be the first place I check for more information about what said tool is doing.

CachedConfiguration is just about Hadoop configs, AFAICT. It behaves per normal HDFS client rules: it uses the default filesystem if you don't give it a full url. On most hdfs installs that's storing into HDFS. I also tested making it with a local filesystem.
Do you mean note like with a log message?
I figured in 1.6, it's better to keep things simple and output with normal HDFS apis. This will normally be used in response to an error and the missing file will be in a particular HDFS instance.

Oh! you mean that the "path" component is a FileSystem URL and will default to the one in your Hadoop configs.
I'll have to see if commons-cli will let me put a description of unparsed args. Would it be terrible if that part of the help message could only be on the later branches when we have jcommander?

This will create a file in HDFS because CachedConfiguration will include the HDFS conf files too, right? It would be good to note where the empty rfile will be created. Beware of multi-volume changes in the 1.6 merge too

Could use Path.getFileSystem() in loop. This will help w/ case where user specifies fully qualified URI. Thought of this after reading Josh's comments.

What would a unit test cover? I think Keith's idea of a IT is likely to be more useful.
Success criteria is scan completes with no errors? (i.e. does not check the values actually returned)

yeah, thats what I was thinking. Success is Accumulo not blowing up when scanning an empty file.

Since Accumulo does not normally create empty RFiles, its not a well tested thing. The RFile unit test excercises creating an empty rfile and seeking it. This ensures that an empty rfile is readable. I am wondering if its worthwhile to have an IT that covers the use case this utility is intended for. Could have an IT that offlines a table, replaces one of its files with an empty rfile, onlines, and then scans.

Worth noting that in later version we switched away from commons-cli in favor of jcommander.
Also, can you add a unit test?
