Mismatch in number of rows imported into cassandra table (COPY command)

I am trying to dump csv file into cassandra table using COPY command. But, number of rows in my csv file and number of rows in cassandra is not consistent.
Number of rows in CSV files : 49765 (excluding header)
Number of rows in cassandra table:
cqlsh:test_df> select Count(*) from test_table;
count
-------
46982
(1 rows)
Warnings :

i did some googling, and it seems like some cassandra-driver issue AttributeError: 'NoneType' object has no attribute 'add_timer' but not really sure how to fix this
