Subject Spark 1.6.1 and regexp_replace
Date Tue, 09 Aug 2016 16:18:19 GMT
I'm having a strange behaviour with regular expression replace, I'm trying
to remove the spaces with trim and also remove the spaces when they are
more than one to only one.

Given a string like this "   A  B   " with trim only I got "A  B" so
if I add regexp_replace I got "  A B".

Text1 is the column so I did

df.withColumn("Text1", expr ( "trim(regexp_replace(Text1,'\\s+',' ') )) )

Also tried another expressions with no luck either

Any idea?
