Praveena updated SPARK-26699:
-----------------------------
    Description: 
Hi,

 

When i run my job in Local mode (meaning as standalone in Eclipse) with same 
parquet input files, the output is -

 

locations
 --------------------
 [[[true, [[, phys...
 [[[true, [[, phys...
 [[[true, [[, phys...
 null
 [[[true, [[, phys...
 [[[true, [[, phys...
 [[[true, [[, phys...
 [[[true, [[, phys...
 [[[true, [[, phys...
 [[[true, [[, phys...

 

But when i run the same code base with same input parquet files in the YARN 
cluster mode, my output is as below -

--------------------
 locations
 --------------------
 [*WrappedArray*([tr...
 [*WrappedArray*([tr...
 [WrappedArray([tr...
 null
 [WrappedArray([tr...
 [WrappedArray([tr...
 [WrappedArray([tr...
 [WrappedArray([tr...
 [WrappedArray([tr...
 [WrappedArray([tr...

Its appending WrappedArray :(

I am using Apache Spark 2.3.2 version and the EMR Version is 5.19.0. What could 
be the reason for discrepancies in the output of certain Table columns ?

I am using Apache Spark 2.3.2 version and the EMR Version while cluster is 
5.19.0. What could be the reason for discrepancies in the output of certain 
Table columns ?
