Subject [jira] [Resolved] (IMPALA-5231) S3 build fails because memory estimates changes
Date Thu, 20 Apr 2017 23:19:04 GMT

Tim Armstrong resolved IMPALA-5231.
-----------------------------------
    Resolution: Fixed



IMPALA-5231: skip test_explain_level on non-HDFS systems

Some details of the plans change if we're not running against a 3-node
minicluster. The point of these tests is to avoid unintended changes
to the explain format, so we don't need to run it against all FSes.
