Talend - tCacheIn / tCacheOut throws null pointer exception -


i working on big data spark requirement have use tcacheout , tcachein. attached job screen shot working fine in 1 scenario when tcacheout has nothing store i.e. filter not allowing flow row next component, throws null pointer exception.

enter image description here

i know, there other alternatives write output in disk , read again @ next step don't want because disk read , write overhead.

how can handle null pointer exception in case?

suppose in tfileinputdelimited having 2 columns i.e. name , age. in tfilterrow have 2 conditions name not equals null , operator name equals "john". have connected tfilterrow component tcacheout 'filter' flow. connect tfilterrow tdie or twarn reject flow.
