esplodere funzione nel alveare

Question

ho i seguenti dati di esempio e sto cercando di esplodere in alveare .. ho usato scissione ma so che mi manca qualcosa ..

["[[-80.742426,35.23248],[-80.740424,35.23184],[-80.739583,35.231562],[-80.735935,35.23041],[-80.728624,35.228069],[-80.727753,35.227836],[-80.727294,35.227741],[-80.726762,35.227647],[-80.726321,35.227594],[-80.725687,35.227544],[-80.725134,35.227535],[-80.721502,35.227615],[-80.691298,35.216202],[-80.688009,35.215396],[-80.686516,35.215016],[-80.598433,35.234307]]"] 

ho usato la query di seguito

select explode (split (col, ',')) da sample2;
e il risultato è questo

 ["[[-80.742426 
     35.23248] 
     [-80.740424 
     35.23184]

     35.208806] 
     [-80.598433 
     35.234307]]"] 

ne ho bisogno in seguito formato

Qualsiasi aiuto qui ..?

Answer 1

I dati sono impostati come array di array e si desidera esplodere i dati solo al primo livello, quindi utilizzare LATERAL VIEW explode(colname) per esplodere al primo livello.

Di seguito è la query SELECT con explode():

select col1 from sample2 LATERAL VIEW explode(col) explodeVal AS col1; 

output generato dai dati di input impostato come di seguito:

[-80.742426,35.23248] 
[-80.740424,35.23184]
