To add to Dennis' comment above, you can skip the first line from being inserted into your table if you're using a CSV SerDe like so:

CREATE EXTERNAL TABLE cases (
  id INT,
  case_number STRING,
  name STRING,
)
ROW FORMAT SERDE 'org.apache.hadoop.hive.serde2.OpenCSVSerde'
STORED AS TEXTFILE
LOCATION '/hdfs/path'
tblproperties("skip.header.line.count"="1");

The operative line being:

tblproperties("skip.header.line.count"="1")
