1. Installing Presto Admin
Prerequisites: Python 2.6 or Python 2.7
Note
For Amazon EMR, use the online installer instead of the offline installer (see Advanced Installation Options).
Note
Omit the use of ‘sudo’ when the prestoadmin scripts and presto-admin commands when the root user is selected as the prestoadmin user.
Note
The sudo setup for a non-root user has a security hole where the presto-admin non-root user requires the ability to run /bin/bash as root. The IT organization will need to take the appropriate steps to address this security hole and select which user will be the presto-admin user.
To install presto-admin
:
1. Copy the installer prestoadmin-1.4-SNAPSHOT-offline.tar.bz2
to the location where you want
presto-admin
to run. The recommended installation location is /opt
. Note that presto-admin
does not have to be on the same node(s) where Presto will run, though it does need to have SSH access to all of the nodes in the cluster.
2. Extract and sudo run the installation script from within the prestoadmin
directory.
$ tar xvf prestoadmin-1.4-SNAPSHOT-offline.tar.bz2
$ cd prestoadmin
$ sudo ./install-prestoadmin.sh
The installation script will create a presto-admin-install
directory and an
executable presto-admin
script. Make sure to run the installation script
with sudo when the presto-admin user is non-root.
3. Verify that presto-admin
was installed properly by running the
presto-admin
help. Please note that it is necessary to run all
presto-admin
commands with sudo:
$ sudo ./presto-admin --help
Please note that you should only run one presto-admin
command on your
cluster at a time.
