}
```

## Description

`create_bulk_import` failed with an error.

## Cause

Job is executing the same exact query twice will cause two distinct
queries to be executed on Treasure Data.


```ruby
print(f'Writing to table {schema_name}.{table_name}') session_name = "session-%d" % (int(time.time()),) 
bulk_import = self.tdclient.create_bulk_import(session_name, schema_name, table_name)
```

session_name was not unique which caused to fail.

## Resolution

Submit a job with unique session_name. Add the random number to the
session name.


```ruby
print(f'Writing to table {schema_name}.{table_name}') session_name = "session-%d-%d" % (int(time.time()),random.randint(1,10001)),) 
bulk_import = self.tdclient.create_bulk_import(session_name, schema_name, table_name)
```
