azure.datalake.store.AdlFileSystem not found in Spark

I am trying to use spark sql to query a csv file placed in Data Lake Store. when I query i am getting "java.lang.ClassNotFoundException: Class com.microsoft.azure.datalake.store.AdlFileSystem not found".

How can I use spark sql to query a file placed in Data Lake Store? Please help me with a sample.

Example csv:

Id     Name     Designation
1      aaa      bbb
2      ccc      ddd
3      eee      fff

Thanks in advance, Sowandharya

Solution

  • Presently HDInsight-Spark Clusters are not available with Azure Data Lake Storage. Once we have the support it would work seamlessly. In the mean time you can try and use ADL Analytics to the same job on ADLS using U-SQL queries. For reference please visit the link: https://azure.microsoft.com/en-us/documentation/articles/data-lake-analytics-get-started-portal/ We are working for the support and it is currently targeted for some time prior to summer 2016. Hope it helps.

    Thanks, Sourabh.
