Hello all,
Could someone please help me figure out what wrong with my query that
I'm running over Parquet tables? the query has the following form:
weird_query = "SELECT a._example.com/aa/1.1/aa_,
b._example.com/bb/1.2/bb_ FROM www$aa@aa a LEFT JOIN www$bb@bb b ON
a.http://example.de/cc=b.column";
I got the exception: /"failure: ``union'' expected but
ErrorToken(illegal character) found"/ on the position of equal symbol "="
So I tried to backtick the column names but got the same exception in
the same position (i.e. "=" position):
weird_query = "SELECT a._`example.com/aa/1.1/aa`_,
b._`example.com/bb/1.2/bb_` FROM www$aa@aa a LEFT JOIN www$bb@bb b ON
a.`http://example.de/cc`=b.`column`
I tried to google the list of illegal characters on SparkSQL but didn't
find any.
Cheers,
