Hi Shim,
Now it works perfectly. Thank you so much. Actually, I am from Java background
and learning the Scala.
Thanks and Regards,

Hello Muhammad.
Please check your bank-full.csv file first and you can filter item length in
your scala code for example val bank = bankText.map(s => s.split(";")).filter(s
=> (s.size)>5).filter(s => s(0) != "\"age\"")
Hope this helps.

Try to debug your code in IDE. You should look at your array s since it
complains about array index.
Thanks,Wd

Hi All,
I have the following Scala code (taken from https://zeppelin.apache.org/
docs/0.6.2/quickstart/ tutorial.html#data-retrieval) that deals with the sample
Bank-details data:
------------------------------ -----------------------------*
------------------------------ ------------------------------ --------
val bankText = sc.textFile("/home/asif/ zeppelin-0.6.2-bin-all/bin/
bank-full.csv")
case class Bank(age:Integer, job:String, marital:String, education:String,
balance:Integer)
// split each line, filter out header (starts with "age"), and map it into Bank
case class
val bank = bankText.map(s=>s.split(";")). filter(s=>s(0)!="\"age\""). map(
s=>Bank(s(0),
s(1).replaceAll("\"", ""),
s(2).replaceAll("\"", ""),
s(3).replaceAll("\"", ""),
s(5).replaceAll("\"", "")
)
)
// convert to DataFrame and create temporal table
bank.toDF().registerTempTable( "bank")
------------------------------ -----------------------------*
------------------------------ ------------------------------ --------The above
code segment runs successfully. However, when I am trying to execute the
following line of code: bank.collect(), I am getting the following error:
org.apache.spark. SparkException: Job aborted due to stage failure: Task 1 in
stage 6.0 failed 1 times, most recent failure: Lost task 1.0 in stage 6.0 (TID
7, localhost): java.lang. ArrayIndexOutOfBoundsException : 2
at $anonfun$3.apply(<console>:91)
at $anonfun$3.apply(<console>:89)
Moreover, I cannot execute the below SQL queries, but getting the same error
message (i.e., ArrayIndexOutOfBoundsException : 2 ):
1. %sql select age, count(1) from bank where age < 30 group by age order by
age2. %sql select age, count(1) from bank where age < ${maxAge=30} group by age
order by age3. %sql select age, count(1) from bank where
marital="${marital=single, single|divorced|married}" group by age order by age
Note: However, when I am executing the following SQL statements I am not
getting any error:
1. %sql select age from bank
2. %sql select * from bank
I don't understand what's wrong I am doing here! Please help me, someone, to
get rid of it.
Thanks and Regards,
