def install(rpm_specifier):
"""
Copy and install the presto-server rpm to all the nodes in the cluster and
configure the nodes.
The topology information will be read from the config.json file. If this
file is missing, then the coordinator and workers will be obtained
interactively. Install will fail for invalid json configuration.
The catalog configurations will be read from the local catalog directory
which defaults to ~/.prestoadmin/catalog. If this directory is missing or empty
then no catalog configuration is deployed.
Install will fail for incorrectly formatted configuration files. Expected
format is key=value for .properties files and one option per line for
jvm.config
Parameters:
rpm_specifier - String specifying location of presto rpm to copy and install
to nodes in the cluster. The string can specify a presto rpm
in the following ways:
1. 'latest' to download the latest release
2. Url to download
3. Version number to download
4. Path to a local copy
If rpm_specifier matches multiple forms, it is interpreted as the form with
highest precedence. The forms are listed from highest to lowest precedence
(going top to bottom) For example, if the rpm_specifier matches the criteria
to be a url to download, it will be interpreted as such and will never be
interpreted as a version number or a local path.
Before downloading an rpm, install will attempt to find a local
copy with a matching version number to the requested rpm. If such
a match is found, it will use the local copy instead of downloading
the rpm again.
--nodeps - (optional) Flag to indicate if server install
should ignore checking Presto rpm package
dependencies. Equivalent to adding --nodeps
flag to rpm -i.
--no-config-update - pass this in order to avoid server update after installation
