I am trying to mirror set of directories from HDP 2.3.4 to HDP 2.5 and I am using Falcon's HDFS-Mirroring extension to do this. However, when I run the job it fails. When I took a close look at the error, it seems like the extension libraries which are supposed to be under HDFS path "/apps/falcon/extensions/hdfs-mirroring/libs/runtime" are missing. The same is true of all falcon extensions. I tried to copy this from the instance where falcon server is running, but the corresponding folders (Ex. /usr/hdp/2.5.0.0-1245/falcon/extensions/hdfs-mirroring/libs/runtime) are also empty.
Where can I find the relevant jar files so that I can copy them into my local instance as well as HDFS?

Remove the falcon service and reinstall it with ambari.

I reinstalled Falcon using Ambari and it did not make any difference. The files under /apps/falcon/extensions/hdfs-mirroring/libs/runtime are still missing.

you need to create directory /apps/falcon/extensions/hdfs-mirroring.

Hi Ram, thanks for the tips. Those directories already exists but empty. So, not sure what else I may need to do. I opened a ticket with Hortonworks support. Will update this forum once I have a resolution.

I am also facing the similar kind of issue.
