I'm already having a MySQL table in my local machine (Linux) it self, and I have a Hive external table with the same schema as the MySQL table. I'm trying to import data from MySQL table to my Hive external table and I'm using sqoop for this. But then the problem is, whenever a new record is being added to the MySQL table, it doesn't update the Hive external table automatically? This is the sqoop import command I'm using: sqoop import --connect jdbc:mysql://localhost:3306/sqoop --username root -P --split-by id --columns id,name,age,salary --table customer --target-dir /user/chamith/mysqlhivetest/ --fields-terminated-by "," --hive-import --hive-table test.customers Am I missing something over here? Or how can this be done? Any help could be appreciated. ... View more

I'm still a noob in this world, so bare with me if there are any misconceptions. What have I done so far is, I've setup Hadoop and Hive in my linux enviroment and I'm trying to extract data from an HDFS file into my Hive table. This is how the log line looks like: apache2013-10-09T14:04:32Zphp129.124.201.110/EKEE.php20019705910Mozilla/5.0 (X11; Linux i686) AppleWebKit/534.24 (KHTML, like Gecko) Chrome/11.0.696.50 Safari/534.24 This my Hive query: CREATE EXTERNAL TABLE LogParserSample( logtype STRING) ROW FORMAT SERDE 'org.apache.hadoop.hive.contrib.serde2.RegexSerDe' WITH SERDEPROPERTIES ( 'input.regex' = '^([\w\-]+)' ) STORED AS TEXTFILE LOCATION '/mypath/'; When I did execute the above the table got created successfully. But then when I tried to query the data from that table using a SELECT statement, I'm getting null instead of the word apache. For this instance, I'm trying to extract the word apache from the above log line. But then I tried executing the same regex in rubular, the outcome was correct as I expected. I'm unable to figure out why! Have I missed anything trivial above? Any help could be appreciated. Thanks! ... View more
