Cloudera Manager Integration

Known Cloudera Manager integration issues.

CSD distribution/activation fails on mixed-OS clusters when there are third-party parcels running on OSs that are not supported by Cloudera Data Science Workbench

For example, adding a new CDSW gateway host on a RHEL 6 cluster running RHEL-6 compatible parcels will fail. This is because Cloudera Manager will not allow distribution of the RHEL 6 parcels on the new host which will likely be running a CDSW-compatible operating system such as RHEL 7.

Workaround: To ensure adding a new CDSW gateway host is successful, you must create a copy of the 'incompatible' third-party parcel files and give them the corresponding RHEL 7 names so that Cloudera Manager allows them to be distributed on the new gateway host. Use the following sample instructions to do so:
  1. SSH to the Cloudera Manager Server host.
  2. Navigate to the directory that contains all the parcels. By default, this is /opt/cloudera/parcel-repo.
    cd /opt/cloudera/parcel-repo
  3. Make a copy of the incompatible third-party parcel with the new name. For example, if you have a RHEL 6 parcel that cannot be distributed on a RHEL 7 CDSW host:
    cp <PARCELNAME.cdh5.x.x.p0.123>-el6.parcel <PARCELNAME.cdh5.x.x.p0.123>-el7.parcel
  4. Repeat the previous step for parcel's SHA file.
    cp <PARCELNAME.cdh5.x.x.p0.123>-el6.parcel.sha <PARCELNAME.cdh5.x.x.p0.123>-el7.parcel.sha
  5. Update the new files' owner and permissions to match those of existing parcels in the /opt/cloudera/parcel-repo directory.
    chown cloudera-scm:cloudera-scm <PARCELNAME.cdh5.x.x.p0.123>-el7.parcel
    chown cloudera-scm:cloudera-scm <PARCELNAME.cdh5.x.x.p0.123>-el7.parcel.sha
    chmod 640 <PARCELNAME.cdh5.x.x.p0.123>-el7.parcel
    chmod 640 <PARCELNAME.cdh5.x.x.p0.123>-el7.parcel.sha
You should now be able to add new gateway hosts for Cloudera Data Science Workbench to your cluster.

Cloudera Bug: OPSAPS-42130, OPSAPS-31880

CDSW Service health status after a restart does not match the actual state of the application

After a restart, the Cloudera Data Science Workbench service in Cloudera Manager will display Good health even though the Cloudera Data Science Workbench web application might need a few more minutes to get ready to serve requests.
