Re: [geowave-dev] Geowave analytics options

Thanks for pointing that out Scott. I actually haven't run DBScan myself using the shaded jar produced by activating the 'analytics-singlejar' profile, but it looks to me, at least regarding your experience with an unrecognized CLI operation, that there's an issue with running analytics through GeoWaveMain in 0.8.9-SNAPSHOT.  The analytics operations simply don't seem to be provided within META-INF/services.  Its a very easy fix at least, I just committed the file with the SPI operation provider that should get you past this error.

I do know Eric's been running DBScan recently, but probably through a different means than this? Eric, should he just be using a different packaging?

We are trying to move toward everything including the analytics running through GeoWaveMain, but we aren't fully there yet (apparently).  Let us know if this works for you.

  I tried out the sample command to run the dbscan analytic against the geolife tables I loaded into GeoWave. However, when I run the command: 

yarn jar geowave-analytic-mapreduce-0.8.9-SNAPSHOT-analytics-singlejar.jar  -dbscan  -n geowave.geolife -u geowave -p hadoop -z FQDN:2181 -i accumulo -emn 2 -emx 6 -pd 1000 -pc mil.nga.giat.geowave.analytic.partitioner.OrthodromicDistancePartitioner -cms 10 -orc 4 -hdfsbase /user/geolife -b bdb4 -eit geolife

I get the following: ERROR cli.GeoWaveMain: Unable to parse operation

org.apache.commons.cli.UnrecognizedOptionException: Unrecognized option: -dbscan

Is dbscan a different option now? Is there a list of the proper options for all of the analytics (such as KMeans, Nearest Neighbors, etc)? Am I just overlooking something in the docs?
