Hi All,
I was trying to create indexes on HDFSDirectory. So I tried to use
lucene-hdfs-directory-4.7.0 but it seems to be incompatible with
lucene-5.2.0. The class HdfsDirectory requires to create an instance of
BufferedIndexOutput which has been deprecated in the lucene-5.2.0 hence my
application is repeatedly failing with NoClassDefFoundError exception.
Following is the stack trace:
Exception in thread "main" java.lang.NoClassDefFoundError:

at com.poc.lucene.client.IndexFieldClient.main(IndexFieldClient.java:17)
Can someone guide me to sort out this problem? Or help to understand the
correct way to create indexes on HDFS using lucene? Is Solr the only way to
create indexes on HDFS using Lucene?
Thanks in advance.
Regards,
Sandeep
