    Description

      This is the failure when I'm trying to run mongodump against a sharded cluster:

      $ ./mongodump --version
      		 
      mongodump version: 100.1.1
      		 
      git version: 8bca136c2a0e0daa3947df31c0624c5615f9aa02
      		 
      Go version: go1.12.17
      		 
         os: linux
      		 
         arch: amd64
      		 
         compiler: gc
      		 
       
      		 
      $ ./mongodump --uri "mongodb+srv://xxx:xxx@cluster1.fu4ty.mongodb.net/?authSource=admin"
      		 
      2020-08-22T12:19:29.097+1000    Failed: can't create session: error configuring the connector: a direct connection cannot be made if multiple hosts are specified

      This appears to be a bug as the same command works fine with mongodump v4.2:

      $ /var/lib/mongodb-mms-automation/mongodb-linux-x86_64-4.2.3-ent/bin/mongodump --version
      		 
      mongodump version: r4.2.3

         compiler: gc
      		 
      $ /var/lib/mongodb-mms-automation/mongodb-linux-x86_64-4.2.3-ent/bin/mongodump --uri "mongodb+srv://xxx:xxx@cluster1.fu4ty.mongodb.net/?authSource=admin"

      Same error is thrown if a legacy mongodb:// URI is specified with multiple mongos listed.

      It appears that the workarounds are either:

      • Use an older version of the tools
      • Or use a mongodb:// URI with a single mongos specified
