Known Issues and Limitations

  • Due to Drill version changes (3-digit to 4-digit), you cannot upgrade from Drill in MEP 7.0.0 (Drill 1.16.1) to Drill in MEP 7.0.1 (Drill or later. You must perform a new installation of Drill. Alternatively, if you are running Drill on CentOS or RHEL, you can issue the following command as a workaround to upgrade Drill:
    rpm -Uv --<old-package> <path/to/packages>/*.rpm

    See Upgrading Drill.

  • Older versions of Drill, such as Drill 1.10.0, supported the HBase plug-in, but Drill versions 1.11.0 through 1.16.0.x do not support queries on HBase tables.
