HDFS as Deep Storage

This guide helps to setup HDFS as deepstorage for Pinot Segment.
To use HDFS as deep storage you need to include HDFS dependency jars and plugins.
Server Setup
Configuration.
pinot.server.instance.enable.split.commit=true
pinot.server.storage.factory.class.hdfs=org.apache.pinot.plugin.filesystem.HadoopPinotFS
pinot.server.storage.factory.hdfs.hadoop.conf.path=/path/to/hadoop/conf/directory/
pinot.server.segment.fetcher.protocols=file,http,hdfs
pinot.server.segment.fetcher.hdfs.class=org.apache.pinot.common.utils.fetcher.PinotFSSegmentFetcher
pinot.server.segment.fetcher.hdfs.hadoop.kerberos.principle=<your kerberos principal>
pinot.server.segment.fetcher.hdfs.hadoop.kerberos.keytab=<your kerberos keytab>
pinot.set.instance.id.to.hostname=true
pinot.server.instance.dataDir=/path/in/local/filesystem/for/pinot/data/server/index
