1. Hadoop HDFS Commands. In this tutorial, we are going to learn the most important and frequently used Hadoop HDFS commands with the help of which we will be able to perform HDFS file operations like copying the file, changing files permissions, viewing the file contents, changing files ownership, creating directories, etc. In this Hadoop Commands tutorial we have mentioned the most Read and Analyze Hadoop Sequence File. This example shows how to create a datastore for a Sequence file containing key-value data. Then, you can read and process the data one block at a time. Sequence files are outputs of mapreduce operations that use Hadoop ®. The following examples show how to use org.apache.hadoop.fs.FileSystem.These examples are extracted from open source projects. You can vote up the examples you like and your votes will be used in our system to produce more good examples. I am thinking to create a sequence file for the same to avoid small files problem which will be indexed using Solr. Questions: 1. I read there is "kite-morphlines-hadoop-sequencefile" morphline command that can be used to read and index it into Solr. Can anyone share any working example of the same ? 2.
