Solution For "Error: java.io.IOException: org.apache.parquet.io.ParquetDecodingException: Can not read value at 0 in block -1 in file" in HDFS
This is due to the Schema Revolution feature of parquet files and the column name of that parquet file may have changed before. so try to apply `set parquet.column.index.access=true` and the issue is solved.
