      1) create a file huh.tsv (see attachment)

      2) execute the following load...

      $ mongoimport -d local --type tsv --headerline \
      --stopOnError --drop -c huh -file ./huh.tsv -v

      3) mongo local should return 5 rows but we only get the following..

      $ mongo local
      MongoDB shell version: 2.2.2
      connecting to: local
      > db.huh.find()

      { "myId" : 1 }

      >

      I have attached the log file with verbose logging turned on below. We only get the dups messages with verbose turned on. I suspect you might also see this if you tried to use the --dbpath to directly access the files. I have seen other bugs mention that using the tool that way produces more output then in client/server mode.

      When importing a simple file with 5 unique rows in it into a new container using mongoimport (I will give examples below into a new container). The import tool says all went well, but only the first row is is saved. I was able to produce this behavior for TSV, CSV and JSON files.

      Staring up the mongodb amazon instance from the amazon market place and upgrading to mongodb 2.2.2 via yum would be the surest way to duplicate what I was seeing. To be specific I was using the public Amazon Instance ID: ami-62da7c0b as a starting point.
