Subject [jira] [Created] (SENTRY-1044) Tables with non-hdfs locations breaks HMS startup
Date Mon, 01 Feb 2016 12:22:39 GMT
Harsh J created SENTRY-1044:
-------------------------------

             Summary: Tables with non-hdfs locations breaks HMS startup
                 Key: SENTRY-1044
                 URL: https://issues.apache.org/jira/browse/SENTRY-1044
             Project: Sentry
          Issue Type: Bug
          Components: Hdfs Plugin
    Affects Versions: 1.6.0
            Reporter: Harsh J
            Priority: Critical


To repro, create any table with location on s3a, file:///, etc., and enable HDFS Sync. It
will cause the plugin to go into an invalid state with the below exception:

We check parsed paths for nulls before we add them to the PathsUpdate object in DbTask and
PartitionTask, but this is omitted accidentally in TableTask.
