| NAME |
| ---- |
| sqoop - The SQL-to-Hadoop database import/export tool |
| |
| SYNOPSIS |
| -------- |
| 'sqoop' <tool-name> <tool-options> |
| |
| DESCRIPTION |
| ----------- |
| Sqoop is a tool designed to help users of large data import existing |
| relational databases or mainframe datasets into their Hadoop clusters. |
| Sqoop interfaces with |
| databases via JDBC, importing the contents of tables into HDFS while |
| generating Java classes so users can interpret the table's schema. |
| Sqoop can also run in reverse, exporting records back from HDFS to a |
| relational data store. |
| |
| Both SequenceFile and text-based targets are supported. Sqoop |
| also supports high-performance imports from select databases including MySQL. |
| |
| OPTIONS |
| ------- |
| |
| Sqoop must be run with a particular tool specified. The options for |
| each tool depend on which tool is chosen. |
| |
| Run 'sqoop help' for a list of all available tools. |
| |
| Run 'sqoop help <tool-name>' for usage instructions for a particular |
| tool. Additional usage instructions are available for each tool in the |
| manual. e.g. 'sqoop-import(1)'. |
| |
| ENVIRONMENT |
| ----------- |
| |
| JAVA_HOME:: |
| As part of its import process, Sqoop generates and compiles Java code |
| by invoking the Java compiler *javac*(1). As a result, JAVA_HOME must |
| be set to the location of your JDK (note: This cannot just be a JRE). |
| e.g., +/usr/java/default+. Hadoop (and Sqoop) requires Oracle Java 1.8 which |
| can be downloaded from http://www.oracle.com/technetwork/java/index.html. |
| |
| HADOOP_COMMON_HOME:: |
| The location of the Hadoop Common files (specifically the bin/hadoop executable). |
| If you installed Hadoop via RPM or DEB, this is in +/usr/lib/hadoop+. |
| |
| HADOOP_MAPRED_HOME:: |
| The location of the Hadoop MapReduce files (specifically the JAR files). |
| If you installed Hadoop via RPM or DEB, this is in +/usr/lib/hadoop-mapreduce+. |
| |
| HIVE_HOME:: |
| If you are performing a Hive import, you must identify the location of |
| Hive's jars and configuration. If you installed Hive via RPM or DEB, |
| these are in +/usr/lib/hive+. |
| |
| SEE ALSO |
| -------- |
| |
| The _Sqoop User Guide_ is available in HTML-form in '/usr/share/doc/sqoop/' |
| (if you installed via RPM or DEB), or in the 'docs/' directory if you |
| installed from a tarball. |
