             Summary: LOAD DATA should not try to load hidden files for Iceberg tables
                 Key: IMPALA-11864
                 URL: https://issues.apache.org/jira/browse/IMPALA-11864
             Project: IMPALA
          Issue Type: Bug
          Components: Frontend
    Affects Versions: Impala 4.3.0
            Reporter: Riddhi jain
            Assignee: Tamas Mate
             Fix For: Impala 4.3.0


Steps to reproduce: # Create an iceberg table
 # Try to load data into the table from folder which has both hidden files as well *.parq file

Example queries ran:
{code:java}
CREATE TABLE iceberg_partitioned_table1 (id int,
bool_col boolean,
timestamp_col timestamp)
stored as iceberg;{code}
{code:java}
LOAD DATA INPATH 's3a://dwx-testdata/impala/sql_test/tests/load_data_inpath/runtime_data/0690a6fa9bfb11ed920c164053429bec/load_data_test/A/impala_data/impala_alltypessmall_data/alltypessmall_parquet_iceberg/year=2009/month=1/' OVERWRITE INTO TABLE iceberg_partitioned_table1;{code}
It is trying to load hidden file instead of ignoring it and hence throw error saying:
{code:java}
AnalysisException: INPATH contains unsupported LOAD format, file '
s3a://dwx-testdata/impala/sql_test/tests/load_data_inpath/runtime_data/0690a6fa9bfb11ed920c164053429bec/load_data_test/A/impala_data/impala_alltypessmall_data/alltypessmall_parquet_iceberg/year=2009/month=1/.hiddenfileforloaddatatest
' has 'This' magic string. {code}
However when there are no hidden files in the folder it loads successfully.
