Description

When converting a Variable Block format EBCDIC file, I got the error "The length of BDW block is too big", tried with following option but still getting same error.

dataframe = spark.read.format("cobol").\
option("copybook", util_params["copybook_path"]).\
option("encoding", "ebcdic"). \
option("schema_retention_policy", "collapse_root"). \
option("record_format", "VB"). \
option("is_bdw_big_endian", "true"). \
option("is_rdw_big_endian", "true"). \
option("bdw_adjustment", -4) . \
option("rdw_adjustment", -4) . \
option("generate_record_id", True).\
load(file_path)

**Error:**

WARN BlockManager: Putting block rdd_1_0 failed due to exception java.lang.IllegalStateException: The length of BDW block is too big. Got 1223880942. Header: 200,242,240,242, offset: 0..

java.lang.IllegalStateException: The length of BDW block is too big. Got 1223880942. Header: 200,242,240,242, offset: 0.

Please suggest some way to fix this issue. Can you please share the example where you have tested the VB scenario with EBCDIC file and copybook for reference.
