[jira] [Created] (HADOOP-8691) FsShell can print "Found xxx items"
unnecessarily often
Jason Lowe created HADOOP-8691:
----------------------------------
Summary: FsShell can print "Found xxx items" unnecessarily often
Key: HADOOP-8691
URL: https://issues.apache.org/jira/browse/HADOOP-8691
Project: Hadoop Common
Issue Type: Bug
Components: fs
Affects Versions: 2.0.0-alpha, 0.23.3
Reporter: Jason Lowe
Priority: Minor
The "Found xxx items" header that is printed with a file listing will often appear multiple times in not-so-helpful ways in light of globbing. For example:
{noformat}
$ hadoop fs -ls 'teradata/*'
Found 1 items
-rw-r--r-- 1 someuser somegroup 0 2012-08-06 16:55 teradata/_SUCCESS
Found 1 items
-rw-r--r-- 1 someuser somegroup 5000 2012-08-06 16:55 teradata/part-m-00000
Found 1 items
-rw-r--r-- 1 someuser somegroup 5000 2012-08-06 16:55 teradata/part-m-00001
{noformat}
Seems like it should just print "Found 3 items" once at the top, or maybe not even print a header at all.

[jira] [Commented] (HADOOP-8691) FsShell can print "Found xxx
items" unnecessarily often

Daryn Sharp commented on HADOOP-8691:
-------------------------------------
Just for clarification, it's not really related to globbing but to the general case of multiple args. Bash prints a header (albeit in a different format) for each arg if it's a directory. So the simple fix is to only print the header if the arg is a directory.
