Apress ? Microsoft Polybase Hadoop and Blob Storage Processing Big Data and Cloud Objects-iLLiTERATE | 397.61 MB
This video dives into Microsoft SQL Server?s PolyBase feature for virtualizing data from Apache Hadoop and Azure Blob Storage into SQL Server. From this video you will learn how to configure SQL Server and PolyBase to connect to Azure Blob Storage, including how to make connections to public and secured blob containers. You?ll also learn how to make connections to Hadoop clusters and query data that is stored in Hadoop.
The video begins by showing how to read from and insert data into Azure Blob Storage. From there, you will learn how to connect PolyBase to a Hadoop cluster, whether in Cloudera?s distribution of Hadoop or the Hortonworks Data Platform. Once connected, you will learn how to query data in Hadoop using two methods: streaming and predicate pushdown. Finally, the video provides key tips on troubleshooting Hadoop integrations, including tips on where to look for log data as well as common configuration and data issues.
