------------------------------------------
Thank you for replying [~dongjoon]. Can you help me in understanding whether
the above mentioned PR will resolve the below mentioned issue.
I have another issue with respect to the decimal scale. When i'm trying to read
the below mentioned csv source file and creating an parquet file from that
throws an java.lang.IllegalArgumentException: Invalid DECIMAL scale: -9
exception.
The source file content is
Row(column name)
9.03E+12
1.19E+11
Refer the given code used read the csv file and creating an parquet file:
//Read the csv file
Dataset dataset = getSqlContext().read()
.option(DAWBConstant.HEADER, "true")
.option(DAWBConstant.PARSER_LIB, "commons")
.option(DAWBConstant.INFER_SCHEMA, "true")
.option(DAWBConstant.DELIMITER, ",")
.option(DAWBConstant.QUOTE, "\"")
.option(DAWBConstant.ESCAPE, "
")
.option(DAWBConstant.MODE, Mode.PERMISSIVE)
.csv(sourceFile)
// create an parquet file
dataset.write().parquet("//path.parquet")
