apache pig - StrSplit in Pig functions -

Can someone explain to me in getting this output down in Pigscript

my input file is down

a.txt 

  aaa.kyl, data, data bbb.kkk, data, data cccccc.hj, data, data qa.dff, data, data

I am writing pig script like this 

  using A = load 'a.txt' PigStorage (',') AS (a1: chararray, a2 : Chararray, a3: chararray); B = format A Generated Flatstone (Strass Limit (A1)), A2, A3;

I do not know how to move forward with it ... I keep it like this. Basically I need all the letters after the dot mark in atom for the first time 

 < (kyl, data, data) (kkk, data, data) (hj, data, data) ( DFF, Data, Data)

Can someone give me the code for this

What you need to do here -

There is a problem of survival here Pig parsing routine, when it encounters dot, because it is considered as operator, then A. See this link for more information.

You can use the Unicode Escape sequence instead for the dot: \ u002E However it should also avoid slash and put in single quoted string.

The code below will work for you and you can fix it according to your convenience - 

  A = load 'A.TXTT' will be used in pygraphoges (' , ') AS (A1: Chararay, A2: Chararai, A3: Chararay); B = format as a Generated Flaton (Strass Limit (A1, '\\ u002E')) (A1: Charray, A1F1: Chararay), A2, A3; C = FOREACH B1A1F1, A2, A3;

Hope it helps.

Is it possible to specify a dependency on another gradeal project in the granular (in android studios) outside the current project limits? For example, with a relative path like this: dependence {collection project ('../../ stdlib / dagger'}} MyApp (path / user / foo / workspace / mypad) The app (Path / User / Foo / Workspace / MyPass / App) And I have an Android Library Project with 3 subdomules: stdlib (path is / user / foo / Utilities (Path / User / Foo / Workspace / Stadlib / Utilis) http (Path / User / Foo / Workspace / Stadlib / HT) / Li> What I have to do is compile the Dagger, Util, http module in the MyApp project.
