      2. Truncate dashboard summaries table: mysql> delete from dashboard_summaries where entity_type='dkt';"

      3. Restart Unravel tw daemon: /etc/init.d/unravel_tw restart

      Workaround

      • Only solution available is to relaunch the crashed browser, and toggle ONLY ONCE, from default view ALL to any of the following labels (Hot, Warm, Cold).

  • HBase:: Namespace missing in HBase table name. (UIX-1736)

  • Migration planning

    • Migration planning reports are not supported for MapR.

    • The following Cloud product/service configurations are not supported:

      • Cloud Product/Service: Azure (IaaS), Azure (HDI)

        Storage Type: Object

        Region: South Africa North, Germany Central, South Africa West, US Gov Iowa, Germany Northeast, US Gov Virginia

      • Cloud Product/Service: Azure (IaaS), Azure (HDI)

        Storage Type: Local

      • Cloud Product/Service: AWS (EMR), AWS (IaaS)

        Storage Type: Object

        Region: AWS GovCloud (US)

    • When Storage Type selected is Object Storage, the minimum disk space required on nodes is ignored when generating the cloud mapping. (REPORT-661)

    • There is no ability to pick the time for the Cluster Discovery Report (you can pick only the date). The time that gets chosen (automatically) does not match the time (automatically) picked for the Chargeback reports. So the data in the charts displayed By App Type, By User and By Queue on the Cluster Discovery Report don’t match the ones on the Chargeback reports. (REPORT-684)

    • Downloaded JSON file for cloud mapping per host and cloud mapping instance display info on Workload fit which is currently not supported. (REPORT-724)

    • Cloud Mapping per Host report for Azure HDI and Azure (IaaS) cloud providers Unravel displays storage on-premises as total storage value and not the actual storage made available by Azure Managed Disks when Storage Type chosen is ‘Local Attached Storage’. (REPORT-728)

    • The “New Report” modal for Cloud Mapping per Host hangs if the user does not provide the Unravel property for cluster type (CDH/HDP) com.unraveldata.cluster.type. (REPORT-731)

    • Actual usage value utilized for figuring out cloud mapping for ‘Cost Reduction’ Strategy is based on last 6 days only of usage.

    • Services and Version Compatibility:

      • Is not supported on CDH versions 6.1.1 and 6.0.1. (REPORT-889)

      • Versions of the components shown may be different from those present in the actual source environment. This is because the ones shown are based on the Distribution Stack's Version and not captured from the actual environment itself.

    • Unravel assumes one core on-premises is equivalent to one cloud vCPU and finds the best possible match without taking into account any performance differences. (CUSTOMER-926)

  • MR:

    • The Move to Queue option in Actions (MR APM) does not work. (PLATFORM-1195)

    • Cluster ID missing for MR apps. (PLATFORM-1434)

    • Failed MR app does have a realuser tag. (PLATFORM-1785)

  • Platform

    • appstatus.AppInfoAccessor: Unable to update ES document. (CUSTOMER-658)

    • Spark worker is missing Azure libraries which causes failure when loading event log and executor logs from Azure.

    • RM Polling is delayed when Yarn kill and move actions are enabled in AutoActions. (PLATFORM-1479)

    • Setting impalad as Impala data source raises errors for invalid HTTP address. (PLATFORM-1444)

  • Queue Analysis: Graph zooming and resetting is not working properly in Edge. (UIX-158)

  • Reports:

    • 6.3 only: Cluster Discovery Report displays OS as Unknown. (Reports-930)

  • Sessions

    • Limitation in HDP cluster: While applying recommendations on a Spark session sometimes we get error like “Could not run the Spark application on the cluster: java.lang.IllegalStateException: hdp.version is not set while running Spark under HDP, please set through HDP_VERSION in spark-env.sh or add a java-opts file in conf with -Dhdp.version=xxx”. The exact reason for this bug is yet to be ascertained.

      Workaround

      1. Open and edit spark-env.sh of the client where unravel is running.

      2. Add a line similar to export “HDP_VERSION=2.6.5.0-292". Make sure to put the proper HDP version in the line.

    • In a MapR cluster, Spark apps fail after tuning recommendations are applied. (SESS-250)

    • Hive: Newly tuned app in MapR is not shown after applying recommendations. (SESS-251)

  • UIX

    • Global search and filter by app name are not working. (UIX-1998)

    • Download CSV and XLS is not working for Tez and Spark APMs. (UIX-1999)

  • Workflow: name search is case-sensitive. (UIX-1904)
