aokolnychyi opened a new pull request #513: Fix concurrency issue in HiveTableOperations when Table is reused
URL: https://github.com/apache/incubator-iceberg/pull/513
 
 
   The same `Table` instance can be shared by multiple jobs meaning that `TableOperations` can be reused. Right now, `doCommit` in `HiveTableOperations` does not check whether `base` is still valid. It checks whether the current metadata location is valid. As a result, if another thread/job that uses the same `HiveTableOperations` updates the current metadata location, this might lead to data corruption.
