What is the method for importing files from HDFS in Hive?
There are several methods for uploading files from the local system to HDFS.
- Utilize Hadoop command line tools, for example hadoop fs -put
. - You can drag and drop files directly into HDFS using the file browser in the Hue interface.
- With Hadoop management tools like Apache Ambari or Cloudera Manager, users can easily upload files to HDFS through the interface.
- Import local files into a Hive table using HiveQL statements, for example:
LOAD DATA LOCAL INPATH '<local_file>' OVERWRITE INTO TABLE <hive_table>;
