      Description

      I'm playing with shard tagging. I'm pretty sure I did something incorrectly, but the shell gave no error and I don't think I should be able to make mongos trigger an assertion by misconfiguring something using shell commands. Here's the details:

      Assertion: 16634:field names of bound

      { yearMonthDay: MinKey }

      do not match those of keyPattern

      { _id: 1.0 }

      databases:

      uhg.claims
      shard key:

      { "_id" : 1 }

      chunks:
      fast1 1
      { "_id" :

      { "$minKey" : 1 }

      } -->> { "_id" :

      { "$maxKey" : 1 }

      } on : fast1

      { "t" : 1, "i" : 0 }

      tag: slow { "yearMonthDay" :

      { "$minKey" : 1 }

      } -->>

      { "yearMonthDay" : "20110719" }

      tag: fast

      { "yearMonthDay" : "20110720" }

      -->> { "yearMonthDay" :

      { "$maxKey" : 1 }

      }

      I'm guessing the bug is "the shell should not have let me do this configuration which resulted in a later assertion triggering". Let me know if you need more info.
