When an Analytics job (e.g. analytics.sh) completes on an Interset Analytics server, the resulting information is placed into <PATH_TBD> and then copied over to the reporting server via scp and placed in /opt/interset/reporting/search/. All indices that are output into this directory are identified by tenant id (e.g. 0).
If no file is present, confirm that ssh keys have been properly generated on the Analytics server, and that the interset user on the Analytics/Ingest server can ssh to the Reporting server without prompting for a password.
An immediate workaround to this issue is to manually copy the files over to the reporting server's /opt/interset/reporting/search/ directory using scp.
