Subject [jira] [Commented] (HADOOP-14220) Enhance S3GuardTool with bucket-info and set-capacity commands, tests
Date Tue, 03 Oct 2017 14:41:00 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-14220?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16189783#comment-16189783
] 

Steve Loughran commented on HADOOP-14220:
-----------------------------------------

Even though this is a javadoc warning, the code is unchanged from trunk. Looks like javadoc
on java 8 allows javadocs to talk about exceptions which aren't explicitly declared as thrown,
*provided a superclass is*

This is the code in question
{code}
  /*
   * @throws Exception on any failure
   * @throws ExitUtil.ExitException for an alternative clean exit
   */
  public abstract int run(String[] args, PrintStream out) throws Exception;
{code}

Tuning the javadocs for java7 would only increase the difference between the two patches,
so I'm going to commit as is.

> Add a diagnostics command to s3guard which does whatever we need to diagnose problems
for a specific (named) s3a url. This is something which can be attached to bug reports as
well as used by developers.
> * Properties to log (with provenance attribute, which can track bucket overrides: s3guard
metastore setup, autocreate, capacity,.... 
> * table present/absent
> * # of keys in DDB table for that bucket?
> * any other stats?
