I am writing code in hiveQL using databricks community edition.
I have loaded the csv dataset files into dbfs, and created hive external table and tried loading table with data from uploaded dbfs file.

CREATE EXTERNAL TABLE IF NOT EXISTS data_table(
Id STRING,
Sponsor STRING,
Status STRING,
Start_Date STRING,
Completion_Date STRING,
Type STRING,
Submission STRING,
Conditions ARRAY<STRING>,
Interventions STRING
)
ROW FORMAT DELIMITED FIELDS TERMINATED BY '|'
LOCATION '/FileStore/tables/CT21/clinicaltrial_2021-1.csv'
TBLPROPERTIES("skip.header.line.count"="2");

result was OK.
But when I queried
select * from data_table

It throws an exception:
Error in SQL statement: IOException: Path: /FileStore/tables/clinicaltrial_2021/mesh.csv is a directory, which is not supported by the record reader when mapreduce.input.fileinputformat.input.dir.recursive is false.

When I checked dbfs directory:
There exists a new directory mesh.csv created by dbfs with many subdirectories with same mesh.csv201197-capture.png

Any help is highly appreciated.

    Hello @PRADEEPCHEEKATLA-MSFT
    I didn't able to check my email in a while. I have resolved the aforementioned error using the command
    SET mapreduce.input.fileinputformat.input.dir.recursive=True.

    Thank you very much for your response.
