[jira] [Created] (HADOOP-8168) empty-string owners or groups causes
{{MissingFormatWidthExeption}} in o.a.h.fs.shell.Ls.ProcessPath()
empty-string owners or groups causes {{MissingFormatWidthExeption}} in o.a.h.fs.shell.Ls.ProcessPath()
------------------------------------------------------------------------------------------------------
Key: HADOOP-8168
URL: https://issues.apache.org/jira/browse/HADOOP-8168
Project: Hadoop Common
Issue Type: Bug
Components: fs
Affects Versions: 0.23.1, 0.24.0
Reporter: Eugene Koontz
In {{adjustColumnWidths()}}, we set the member variable {{lineFormat}}, which is used by {{ProcessPath()}} to print directory entries. Owners and groups are formatted using the formatting conversion {{%-Xs}}, where X is the max length of the owner or group. However, when trying this with an S3 URL, I found that the owner and group were empty (""). This caused X to be 0, which means that the formatting conversion is set to {{%-0s}}. This caused a {{MissingFormatWidthException}} to be thrown when the formatting string was used in {{ProcessPath()}}.
Formatting conversions are described here:
http://docs.oracle.com/javase/1.5.0/docs/api/java/util/Formatter.html#intFlags
The specific exception thrown (a subtype of {{IllegalFormatException}}) is described here:
http://docs.oracle.com/javase/1.5.0/docs/api/java/util/MissingFormatWidthException.html

Make sure that for {{%-Xs}} formatting conversions, {{X}} is greater than 0.

Eugene, I'm uploading a patch tweaking your patch to Daryn's comments. Hope this is OK with you.

fmt.append((maxOwner > 0) ? "%-" + maxOwner + "s " : "%s");

[jira] [Updated] (HADOOP-8168) empty-string owners or groups causes
{{MissingFormatWidthException}} in o.a.h.fs.shell.Ls.ProcessPath()
Posted by "Eugene Koontz (Updated) (JIRA)" <ji...@apache.org>.

----------------------------------
Description:
In {{adjustColumnWidths()}}, we set the member variable {{lineFormat}}, which is used by {{ProcessPath()}} to print directory entries. Owners and groups are formatted using the formatting conversion {{%-Xs}}, where X is the max length of the owner or group. However, when trying this with an S3 URL, I found that the owner and group were empty (""). This caused X to be 0, which means that the formatting conversion is set to {{%-0s}}. This caused a {{MissingFormatWidthException}} to be thrown when the formatting string was used in {{ProcessPath()}}.
Formatting conversions are described here:
http://docs.oracle.com/javase/1.6.0/docs/api/java/util/Formatter.html#intFlags

> In {{adjustColumnWidths()}}, we set the member variable {{lineFormat}}, which is used by {{ProcessPath()}} to print directory entries. Owners and groups are formatted using the formatting conversion {{%-Xs}}, where X is the max length of the owner or group. However, when trying this with an S3 URL, I found that the owner and group were empty (""). This caused X to be 0, which means that the formatting conversion is set to {{%-0s}}. This caused a {{MissingFormatWidthException}} to be thrown when the formatting string was used in {{ProcessPath()}}.
> Formatting conversions are described here:

> The specific exception thrown (a subtype of {{IllegalFormatException}}) is described here:
