Hello Friends,

I created table in hive with help of following command -

CREATE TABLE db.test 
  ( 
     fname STRING, 
     lname STRING, 
     age   STRING, 
     mob   BIGINT 
  ) row format delimited fields terminated BY '\t' stored AS textfile; 

Now to load data in table from file, I am using following command -

load data local inpath '/home/cluster/TestHive.csv' into table db.test;

Problem is, all the rows are getting inserted, and I don't want first row because it contains only column names.

Please suggest me a way to skip first line.

Thanks in advance.

To get this you can use hive's property which is TBLPROPERTIES ("skip.header.line.count"="1") you can also refer example -

CREATE TABLE temp 
  ( 
     name STRING, 
     id   INT 
  ) 
row format delimited fields terminated BY '\t' lines terminated BY '\n' 
tblproperties("skip.header.line.count"="1");

  • Looks like a duplicate stackoverflow.com/questions/15751999/…
  • possible duplicate of Hive External table-CSV File- Header row
  • Working on Hive, but not on Impala.
  • have you created table in Hive and accessing from Impala?
  • No, I used the CREATE TABLE statement with that tblproperty directly on Impala shell. I did not try the statement in Hive and then access the same table from Impala.
