I don't think this is doable using the out of the box regexp_replace() UDF.
That way I would do it, is using a file to create a mapping
Hi Everyone,
I am using hive 0.13! I want to find multiple tokens like hip hop and
rock music in my data and replace them with hiphop and rockmusic -
basically replace them without white space. I have used the regexp_replace
function in hive. Below is my query and it works great for above 2
I don't think this is doable using the out of the box regexp_replace() UDF.
That way I would do it, is using a file to create a mapping between a
regexp and it's replacement and write a custom UDF that loads this file and
applies all regular expressions on the input.
Hope this helps.

hi Viral,
Unless you are strictly bound to change the text to achieve your
objectives... you may actually wish to explore ngrams and context_ngram
combinations to uniquely identify the patterns you want to explore and move
them to a new table for further processinng
Better do it at file level on
