  @service
    name: 'phoenix'
    if: options.phoenix_enabled
  # migration: wdavidw 170908, attempt to simplify package installation

Configure

See Hive/HCatalog Configuration Files

    header: 'Hive Site'
    target: "#{options.conf_dir}/hive-site.xml"

    local: true
    properties: options.hive_site
    merge: true
    backup: true
    mode: 0o644

Env

Enrich the "hive-env.sh" file with the value of the options "opts" and "heapsize". Internally, the environmental variables "HADOOP_CLIENT_OPTS" and "HADOOP_HEAPSIZE" are enriched and they only apply to the Hive client.

Using this functionnality, a user may for example raise the heap size of Hive Client to 4Gb by either setting a "opts" value equal to "-Xmx4096m" or the by setting a "heapsize" value equal to "4096".
