Hi Sarath, Considering your two step approach...
The load command by default searches for file in HDFS, so you are doing the same by following command hive> load data inpath '/user/hduser/dumps/table_dump.csv' overwrite into table table1; instead, you can use 'local' to tell hive that the CSV file is on local file system and not on HDFS, as below hive> load data local inpath '/user/hduser/dumps/table_dump.csv' overwrite into table table1; Hope that helps Kind regards, Keshav C Savant From: Sarath [mailto:sarathchandra.jos...@algofusiontech.com] Sent: Friday, September 28, 2012 11:28 AM To: user@hive.apache.org Subject: Problem loading a CSV file Hi, I have created a new table using reference to a file on HDFS - create external table table1 (field1 STRING, field2 STRING, field3 STRING, field3 STRING, field4 STRING, field5 FLOAT, field6 FLOAT, field7 FLOAT, field8 STRING, field9 STRING) row format delimited fields terminated by ',' location '/user/hduser/dumps/table_dump.csv'; The table got created successfully. But when I try retrieving rows from this table, it returns me nothing. hive> select * from table1; OK Time taken: 0.156 seconds I also tried creating the table first and then loading the HDFS file data into it - hive> create table table1 (field1 STRING, field2 STRING, field3 STRING, field3 STRING, field4 STRING, field5 FLOAT, field6 FLOAT, field7 FLOAT, field8 STRING, field9 STRING) row format delimited fields terminated by ','; OK Time taken: 0.088 seconds But when I try to load data into this table I'm getting below error - hive> load data inpath '/user/hduser/dumps/table_dump.csv' overwrite into table table1; FAILED: Error in semantic analysis: Line 1:17 Invalid path ''/user/hduser/dumps/table_dump.csv'': No files matching path hdfs://master:54310/user/hduser/dumps/table_dump.csv What is going wrong? Is there a different way to load a CSV file using hive? Regards, Sarath. _____________ The information contained in this message is proprietary and/or confidential.
