Spark SQL - java.lang.StackOverflowError after caching table

[Mohamed Nadjib MAMI]

Hi all,
I'm running SQL queries (sqlContext.sql()) on Parquet tables and facing 
a problem with table caching (sqlContext.cacheTable()), using 
spark-shell of Spark 1.5.1.

After I run the sqlContext.cacheTable(table), the sqlContext.sql(query) 
takes longer the first time (well, for the lazy execution reason) but it 
finishes and returns results. However, the weird thing is that after I 
run the same query again, I get the error: "java.lang.StackOverflowError".

I Googled it but didn't find the error appearing with table caching and 
querying.
Any hint is appreciated.
