Hi Vivek Thanks A few more experiments The \\ , \\\ and \\\\ all work correctly if used as following split(reverse(split(reverse(floc),'/')[0]),'[\\.]')[0] (need those square brackets) split(reverse(split(reverse(floc),'/')[0]),'\\\.')[0] (does not need square brackets) split(reverse(split(reverse(floc),'/')[0]),'[\\\\.]')[0] (need those square brackets) From: Vivek Veeramani <vivek.veeraman...@gmail.com> To: user@hive.apache.org; Sanjay Subramanian <sanjaysubraman...@yahoo.com> Sent: Monday, August 24, 2015 1:57 PM Subject: Re: Using SPLIT with DOT(.) delimiter demonstrate funny behavior within a VIEW Hi Sanjay, Try replacing the 4 backslashes with just 2. Usually works with 2 backslashes. Replace this split(reverse(split(reverse(floc),'/')[0]),'\\\\.')[0] as resid with split(reverse(split(reverse(floc),'/')[0]),'\\.')[0] as resid
Please have a look and let us know if that helps.
