Configuration Management

+ +
+ +

Configuration Overview

+ +

All accumulo properties have a default value in the source code. Properties can also be set +in accumulo-site.xml and in zookeeper on per-table or system-wide basis. If properties are set in more than one location, +accumulo will choose the property with the highest precedence. This order of precedence is described +below (from highest to lowest):

+ +

Zookeeper table properties

+ +

Table properties are applied to the entire cluster when set in zookeeper using the accumulo API or shell. While table properties take precedent over system properties, both will override properties set in accumulo-site.xml

+ +

Table properties consist of all properties with the table.* prefix. Table properties are configured on a per-table basis using the following shell command:

+ +
config -t TABLE -s PROPERTY=VALUE
+
+
+ +

Zookeeper system properties

+ +

System properties are applied to the entire cluster when set in zookeeper using the accumulo API or shell. System properties consist of all properties with a yes in the Zookeeper Mutable column in the table below. They are set with the following shell command:

+ +
config -s PROPERTY=VALUE
+
+
+ +

If a table.* property is set using this method, the value will apply to all tables except those configured on per-table basis (which have higher precedence).

+ +

While most system properties take effect immediately, some require a restart of the process which is indicated in Zookeeper Mutable.

+ +

accumulo-site.xml

+ +

Accumulo processes (master, tserver, etc) read their local accumulo-site.xml on start up. Therefore, changes made to accumulo-site.xml must synced across the cluster and processes must be restarted to apply changes.

+ +

Certain properties (indicated by a no in Zookeeper Mutable) cannot be set in zookeeper and only set in this file. The accumulo-site.xml also allows you to configure tablet servers with different settings.

+ +

Default Values

+ +

All properties have a default value in the source code. This value has the lowest precedence and is overridden if set in accumulo-site.xml or zookeeper.

+ +

While the default value is usually optimal, there are cases where a change can increase query and ingest performance.

+ +

ZooKeeper Property Considerations

+ +

Any properties that are stored in ZooKeeper should consider the limitations of ZooKeeper itself with respect to the +number of nodes and the size of the node data. Custom table properties and options for Iterators configured on tables +are two areas in which there aren’t any fail safes built into the API that can prevent the user from making this mistake.

+ +

While these properties have the ability to add some much needed dynamic configuration tools, use cases which might fall +into these warnings should be reconsidered.

+ +

Configuration in the Shell

+ +

The config command in the shell allows you to view the current system configuration. You can also use the -t option to view a table’s configuration as below:

+ +
$ ./bin/accumulo shell -u root
+Enter current password for 'root'@'accumulo-instance': ******
