  - by mannamal

  We are pleased to announce availability of Oracle Loader for Hadoop 1.1.0.0.3, containing bug fixes and performance improvements to Oracle Loader for Hadoop. The updated product can be downloaded from here: http://www.oracle.com/technetwork/bdc/big-data-connectors/downloads/big-data-downloads-1451048.html Note that the Oracle Loader for Hadoop 1.1.0.0.3 kit is a complete kit containing the product and bug fixes. Fixes of the earlier version 1.1 patch releases are also included. Upgrading to Oracle Loader for Hadoop 1.1.0.0.3 (from versions 1.1.x): On the Oracle Big Data Appliance:  1. 1.  Upload the new oraloader rpm to the first Oracle Big Data Appliance server.  For example:   /tmp/oraloader-1.1.0.0.3-1.x86_64.rpm 2.     As the root user, use dcli from the first Oracle Big Data Appliance server to copy the new rpm to all nodes. For example:   #dcli -f /tmp/oraloader-1.1.0.0.3-1.x86_64.rpm  -d /tmp/oraloader-replace.rpm 3. 3.  As the root user, use dcli from the first Oracle Big Data Appliance server to replace the old oraloader rpm with the new one.  For example:  #dcli "rpm -e oraloader ; rpm -Uvh /tmp/oraloader-replace.rpm" On other hardware: 1. 1.  Unzip oraloader-1.1.0.0.3.x86_64.zip at <location of install> 2. 2.  Update OLH_HOME to point to <location of install>/oraloader-1.1.0.0.3

• Welcome!

  Welcome to the Oracle Big Data Connectors blog, which will focus on posts related to integrating data on a Hadoop cluster with Oracle Database. In particular the blog will focus on best practices, usage notes, and performance tips for using Oracle Loader for Hadoop and Oracle Direct Connector for HDFS, which are part of Oracle Big Data Connectors. Oracle Big Data Connectors 1.0 also includes Oracle R Connector for Hadoop and Oracle Data Integrator Application Adapters for Hadoop. Oracle Loader for Hadoop: Oracle Loader for Hadoop loads data from Hadoop to Oracle Database. It runs as a MapReduce job on Hadoop to partition, sort, and convert the data into an Oracle-ready format, offloading to Hadoop the processing that is typically done using database CPUs. The data is thenloaded to the database by the Oracle Loader for Hadoop job (online load) or written out as Oracle Data Pump files for load and access later (offline load) with Oracle Direct Connector for HDFS. Oracle Direct Connector for HDFS: Oracle Direct Connector for HDFS is a connector for high speed access of data on HDFS from Oracle Database. With this connector Oracle SQL can be used to directly query data on HDFS. The data can be Oracle Data Pump files generated by Oracle Loader for Hadoop or delimited text files. The connector can also be used to load data into the database using SQL.

• Loading from Multiple Data Sources with Oracle Loader for Hadoop

  - by mannamal

  Oracle Loader for Hadoop can be used to load data from multiple data sources (for example Hive, HBase), and data in multiple formats (for example Apache weblogs, JSON files).   There are two ways to do this: (1) Use an input format implementation.  Oracle Loader for Hadoop includes several input format implementations.  In addition, a user can develop their own input format implementation for proprietary data sources and formats. (2) Leverage the capabilities of Hive, and use Oracle Loader for Hadoop to load from Hive. These approaches are discussed in our Oracle Open World 2013 presentation.
