Hi Thanuja,
As given in the thread "[DAS 3.0.0 Beta] No FileSystem for scheme: file",
can you add the following properties and try:
<property>
<name>fs.hdfs.impl</name>
<value>org.apache.hadoop.hdfs.DistributedFileSystem</value>
</property>
<property>
<name>fs.file.impl</name>
<value>org.apache.hadoop.fs.LocalFileSystem</value>
</property>
These settings are available out-of-the-box in the sample datasource
configuration in recent DAS packs, any reason why they went missing?
Thanks,
