Filemanager how to only metadata
Hi everyone,
I'm experimenting with OODT filemanager, and wanted to ingest a product file's met into the filemgr catalog.
I don't have the product file on hand, but I do have the metadata.
The filemgr user's guide (ie. http://oodt.apache.org/components/maven/filemgr/user/basic.html) documents how to ingest a product file assuming you actually have the product on hand. However, if I only want to ingest the metadata, how would I go about doing this?
The 'filemgr-client' script seems to not allow ignoring the product reference. In other words, I cannot simply eliminate the "--refs" flag.
> ./filemgr-client --url http://localhost:9000 --operation \
--ingestProduct --productName blah.txt --productStructure Flat \
--productTypeName GenericFile \
--metadataFile file:///usr/local/cas-filemgr-v1.8.0/bin/blah.txt.met \
--refs file:///usr/local/cas-filemgr-v1.8.0/bin/blah.txt
Any tips on how to ingest metadata only?
Thanks!
Rishi

Yep, I think bfost mentioned this, but the best way to take care of it here is two-fold:
1. Just use the InPlaceDataTransferer. It will neglect to transfer the product files (which is what you want since you don't have any)
2. Just pass dummy refs: fefs are only used for cataloging locations of products, and also passed to the data transferer to do with how it likes. If you use a transferer that doesn't bother to transfer, then you're fine there.
Another option would be to use the StdProductCrawler (part of cas-crawler). It expects .met files (in CAS format) and will look for:
Filename
FileLocation
ProductType
To be set to ingest into the FM. If you're using InPlaceDataTransferer, then FileLocation can be a dummy value and it will still work.

See above.
Good luck!
Cheers,
Chris

Hi Chris,
Thanks for your help! I didn't realize '--clientTransfer' was necessary, but I now got the metadata ingest to work.
Thanks!

Sorry, I didn't know you interpreted my recollection of the *exact parameter name* literally. YMMV doing that. The best bet will always be to check the cmd line usage (with no args like you did) for the most up-to-date usage.

None of the above will would because they all omit the use of:
--clientTransfer
NOTE: this parameter tells the File Manager that the FM Client will be doing the actually data transferring, rather than the FM Server.
So, basically what you do is you provide both the switch to turn on client transfer *and* the appropriate data transfer factory. Try:
--clientTransfer --dataTransfer org.apache.oodt.cas.filemgr.datatransfer.InPlaceDataTransferFactory
HTH!

Re: Filemanager how to only metadata

Hi Chris,
The filemgr-client usage statement seems to indicate support only for (--clienTransfer or --dataTransfer) options, not the "--transferFactory" as you suggested.
In any case though, I tried a couple parameter arguments with filemgr-client, but all yield an error saying a product specified with --refs could not be located:
1) ./filemgr-client ... --transferFactory InPlaceDataTransferFactory --refs file:///doesnotexist
2) ./filemgr-client ... --dataTransfer InPlaceDataTransferFactory --refs file:///doesnotexist
3) ./filemgr-client ... --dataTransfer org.apache.oodt.cas.filemgr.datatransfer.InPlaceDataTransfererFactory --refs file:///doesnotexist
4) ./filemgr-client ... --transferFactory InPlaceDataTransfer --refs file:///doesnotexist
For all the above attempts, I see in the filemgr log the following exception:
SEVERE: ingestProduct: DataTransferException when transfering Product: test.h5: Message: Source '/doesnotexist' does not exist
org.apache.oodt.cas.filemgr.structs.exceptions.DataTransferException: java.io.FileNotFoundException: Source '/doesnotexist' does not exist
Do you have any tips on the above usage or why its still looking for a real product file?
Thank you!

Hi -
Thanks for the helpful tips.
I was looking at InPlaceDataTransferer, and it does not seem to have a command line interface (there's no main). Specifically, I looked at the class
"org.apache.oodt.cas.filemgr.datatransfer.InPlaceDataTransferer"
Is there a command-line wrapper already built I can use?
