accumulo-saltstack-pillar

Pillar files to go as defaults with the accumulo-saltstack <https://github.com/accumulo/accumulo-saltstack> and accumulo-saltstack <https://github.com/accumulo/hadoop-salt> projects.

Most of the values are just reflecting the internal defaults of the formulas that are using them. For your own provisioning you can use a modified copy or fork of this.

Master configuration

This particular or any of your pillar projects can be used on a Salt master by pulling it in as-is through an ext_pillar configuration in /etc/salt/master.

ext_pillar:
  - git: master https://github.com/accumulo/accumulo-saltstack-pillar.git

Hadoop and Accumulo configuration

The hadoop and accumulo formulas expose the general (cluster-independent) part of their main configuration files (Hadoop: core-site.xml, hdfs-site.sml, mapred-site.xml, Accumulo: accumulo-site.xml) as pillar keys.

Example:

hadoop:
  config:
    tmp_dir: /var/lib/hadoop/tmp
    directory: /etc/hadoop/conf
    core-site:
      io.native.lib.available:
        value: true
      io.file.buffer.size:
        value: 65536
      fs.trash.interval:
        value: 60

Where the core-site part will appear in core-site.xml as:

<property>
    <name>io.native.lib.available</name>
    <value>True</value>
</property>

<property>
    <name>fs.trash.interval</name>
    <value>60</value>
</property>

<property>
    <name>io.file.buffer.size</name>
    <value>65536</value>
</property>

Please note that host- and cluster-specific values are not exposed (think: fs.default.name)
