scala - Tokenizing strings in a "String RDD" returning another RDD -


i have spark rdd of individual string values, each string formed out of words separated | symbols.

this rdd generated sparksql query, not .textfile(...) load operation.

i can't (unless i'm miss-understanding fundamental) use .flatmap(_.split("|")) operation flattens each string individual characters before applying .split().

however, need .flatmap() in need 1 many mapping. data set potentially large need operation parallelize, hence use of rdds , related operations.

interestingly when processing strings rdds loaded using .textfile(...), .flatmap(...) operation want! i'm guessing there must way...

any or suggestions appreciated!

thanks!

well, not sure understand problem, try help.

in .flatmap(_.split("|")) split breaks words of each line, , @ end flattened. if don't need flatten result, perhaps can use .map(_.split("|")).

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
