CFs should have globally and temporally unique CF IDs to prevent "reusing" data from earlier incarnation of same CF name

    Details

    • Type: Bug
    • Status: Resolved
    • Priority: Major
    • Resolution: Fixed
    • Fix Version/s: 2.1 beta1
    • Component/s: None
    • Labels:
    • Environment:

      OS: Windows 7,
      Server: Cassandra 1.1.9 release drop
      Client: astyanax 1.56.21,
      JVM: Sun/Oracle JVM 64 bit (jdk1.6.0_27)

      Description

      Attached is a driver that sequentially:

      1. Drops keyspace
      2. Creates keyspace
      4. Creates 2 column families
      5. Seeds 1M rows with 100 columns
      6. Queries these 2 column families

      The above steps are repeated 1000 times.

      The following exception is observed at random (race - SEDA?):

      This exception appears in the server at the time of client submitting a query request (row slice) and not at the time data is seeded. The client times out and this data can no longer be queried as the same exception would always occur from there on.

      Also on iteration 201, it appears that dropping column families failed and as a result their recreation failed with unique column family name violation (see exception below). Note that the data files are actually gone, so it appears that the server runtime responsible for creating column family was out of sync with the piece that dropped them:
