  • Cluster Fails to start if /var/tmp/.aster-ports is missing

    Issue: BH-14566

    Details: The cluster reports an Unknown state when stopped abruptly. When in this state during an attempted restart of the cluster, the cluster tries to access .aster-ports to get the logserver port before .aster-ports is copied by the ClusterServicesAction script from the original file, /beehive/config/ports.

    Workaround: Copy .aster-ports manually before restarting the cluster:
    cp /home/beehive/config/ports /var/tmp/.aster-ports
    chmod beehive:beehive /var/tmp/.aster-ports
  • SQL-MapReduce Functions DWT and DWT2D fail with error

    Issue: BH-11415

    Details: The SQL-MapReduce Functions DWT and DWT2D fail with error ERROR: An internal error has occurred. Please contact support at Aster Data. ().

    Workaround: None. Contact your Customer Support Representative.

  • Unpacking aster-db-coordinator rpm file can fail without an available eth0 interface

    Issue: BH-11635

    Details: Unpacking the aster-db-coordinator rpm file can fail when the docker0 bridge is present, but there is not an available eth0 interface.

    Workaround: Have an available ethernet networking interface (for example, eth0) to ensure the installer can successfully unpack the required installation packages.

  • Cannot view disk usage on AMC Dashboard

    BH-10449

    Details: System monitor is reporting incorrect system usage information, therefore this feature is disabled.

    Workaround: None

  • Geometry Functions and PSTParserAFS Function do not work on Aster Execution Engine 7.00.01

    Issue: ANLY-3171

    Details: The three Geometry functions and PSTParserAFS function do not work on Aster Execution Engine 7.00.01.

    Workaround: For the Geometry functions, convert the input for the GeometryOverlay and PointInPolygon functions to well-known text (WKT) format and then load it into either HDFS or the queen node. The GeometryOverlay and PointInPolygon functions will then work.

    There is no workaround for the GeometryLoader and PSTParserAFS functions.

  • Some SQL-MR driver functions do not work in an SSL-enabled cluster

    Issue: CLNT-2708

    Details: The following driver functions do not work in an SSL-enabled cluster:
    • AdaBoost_Drive.sql
    • CoxPH.sql
    • CrossValidation.sql
    • KModes.sql
    • RandomSample.sql
  • AMC puts SQL/MR log files in the /tmp directory, eventually filling up /tmp space

    Issue: BH-10014

    Details: AMC puts some log files in the /tmp directory, which eventually fills up /tmp space. This causes the monitoring service to take remedy action and shuts down the Aster service.

    Workaround: None

  • AMC shows incorrect session user after set role

    Issue: BH-7354

    Details: Statements run by an impersonated user (role) no longer show the impersonated user. AMC shows the user who originally started the sessions.

    Workaround: None

  • ncli sshkeys disable removes keys that are not intra-cluster keys

    Issue: BH-4930

    Details: After using ncli sshkeys disable, a worker or loader node can lose keys that are unrelated to the cluster.

    Workaround: None

  • Changes made by the arcpasswd script are not persistable

    Issue: BH-9773

    Details: If you use the arcpasswd script to change an internal user password, such as _bee_replay, at the next restart the password will not be restored and the replay will fail due to authorization failures.
