Takanobu Asanuma commented on HADOOP-10783:
-------------------------------------------

Uploaded the 5th patch addressing the failed tests. Some comments for modified 
class:
 * TableListing
 {{commons.lang3.text.WordUtils}} has a bug when {{wrapWidth}} is 
Integer.MAX_VAL. (See: LANG-1397) The patch use a workaround to use a large 
enough value instead of Integer.MAX_VAL.

 * ResourceUtils
 {{StringUtils.isAlpha}} breaks compatibility for emptye string. The patch 
handle it.
{code:java}
 org.apache.commons.lang.StringUtils.isAlpha("") // true
 org.apache.commons.lang3.StringUtils.isAlpha("") // false
{code}

> apache-commons-lang.jar 2.6 does not support FreeBSD -upgrade to 3.x needed

> Hadoop-2.4.1 ships with apache-commons.jar version 2.6.
> It does not support FreeBSD (IS_OS_UNIX returns False).
> This is fixed in recent versions of apache-commons.jar
> Please update apache-commons.jar to recent version so it correctly recognizes 
> FreeBSD as UNIX-like system.
> Right now I get in datanode's log:
