[GitBox]

zhaoyanggh opened a new issue #1515:
URL: https://github.com/apache/arrow-rs/issues/1515


   **Describe the bug**
   I want to read the parquet I generated, which get the error when I use the 
"get_row_iter" api, I get this error:
   thread 'main' panicked at 'called `Option::unwrap()` on a `None` value', 
/home/yzhao/.cargo/registry/src/github.com-1ecc6299db9ec823/parquet-11.0.0/src/record/reader.rs:132:52
   
   **To Reproduce**
   Steps to reproduce the behavior:
   This is my schema:
   message table {
     REPEATED group table_info {
       REQUIRED BYTE_ARRAY name;
       REPEATED group cols {
         REQUIRED BYTE_ARRAY name;
         REQUIRED INT32 type;
         OPTIONAL INT32 length;
       }
       REPEATED group tags {
         REQUIRED BYTE_ARRAY name;
         REQUIRED INT32 type;
         OPTIONAL INT32 length;
       }
     }
   }
   
   I can successfully read the parquet if I change the schema to :
   message table {
     REPEATED group table_info {
       REQUIRED BYTE_ARRAY name;
       REPEATED group cols {
         REQUIRED BYTE_ARRAY name;
         REQUIRED INT32 type;
         OPTIONAL INT32 length;
       }
     }
   }
   
   **Expected behavior**
   For my generated parquet file, I can successfully use mac's parquet-tools to 
read them:
