Masood Parvari updated DRILL-2765:
----------------------------------
Attachment: url_column_onetime_value.parquet
url_column_completely_null.parquet
yes of course. I will attach 2 file. the proto file is :
message Log
{
optional string date = 1;
optional string url = 2;
}
in the files,one sample record is written repeatedly. File
url_column_completely_null.parquet, as the name suggests have a complete null
column. File url_column_onetime_value.parquet, in just one record, has value
for 'url' column. The latter can be queried by drill while the former throws a
null pointer exception
> Throwing a NPE on exceuting query against parquet files
