This topic describes the logs generated by the Installer
and Installer Stanzas.
Installer logs are written to the following folder:
/opt/mapr/installer/logs.
The following list describes each log:
<nodename>.log[.x]- Shows installation activities associated with a particular node. Every time you run
the Installer or a Installer Stanza, a new copy of this log is created for each node in the cluster.
When you encounter errors, you should check this log first, and then check the
mapr-installer.log.
- The node log is created only if the software was able to run Ansible successfully on
the node. If incorrect credentials were provided for the root user, or if there was an
issue and Ansible quit before issuing the first logging callback, no log file is created
for the node. If this happens, you must consult
mapr-installer.log.
installer.log[.x]- Logs the REST calls sent to the installer and the database events that the installer
runs. Every time you run the Installer or a Installer Stanza, a new copy of this log is created. If the
log is not present, you might need to restart the installer (
service
mapr-installer restart).
installer-cli.log[.x]- Shows the progress of installation for a Installer
Stanza. Every time you run a Installer Stanza, a new copy
of this log is created.
installer-process.log- Serves as the top-level log file for the Ansible part of the installer. This log is
created by the main Python script that runs the installer backend. This log typically
shows the same information as
mapr-installer.log.
mapr-installer.log[.x]- Shows the progress of Ansible scripts performed by the installer server. This log is
useful if back-end issues prevent the creation of
<nodename>.log.
Every time you run the Installer or a Installer Stanza, a new copy of this log is created.
