The HDFS file path of the directory that the Blaze engine uses to store temporary files. Verify that the directory exists. The YARN user, Blaze engine user, and mapping impersonation user must have write permission on this directory.

Default is

/blaze/workdir

. If you clear this property, the staging files are written to the Hadoop staging directory

/tmp/blaze_<user name>

.

The owner of the Blaze service and Blaze service logs.

When the Hadoop cluster uses Kerberos authentication, the default user is the Data Integration Service SPN user. When the Hadoop cluster does not use Kerberos authentication and the Blaze user is not configured, the default user is the Data Integration Service user.

The minimum value for the port number range for the Blaze engine. Default is 12300.

The maximum value for the port number range for the Blaze engine. Default is 12600.

The YARN scheduler queue name used by the Blaze engine that specifies available resources on a cluster.

The host name and port number for the Blaze Job Monitor.

Use the following format:

Where

<hostname> is the host name or IP address of the Blaze Job Monitor server.
<port> is the port on which the Blaze Job Monitor listens for remote procedure calls (RPC).

For example, enter:

myhostname:9080

Node label that determines the node on the Hadoop cluster where the Blaze engine runs. If you do not specify a node label, the Blaze engine runs on the nodes in the default partition.

If the Hadoop cluster supports logical operators for node labels, you can specify a list of node labels. To list the node labels, use the operators

&&

(AND),

||

(OR), and

!

(NOT).

List of advanced properties that are unique to the Blaze engine. The advanced properties include a list of default properties.

You can configure run-time properties for the Hadoop environment in the Data Integration Service, the Hadoop connection, and in the mapping. You can override a property configured at a high level by setting the value at a lower level. For example, if you configure a property in the Data Integration Service custom properties, you can override it in the Hadoop connection or in the mapping. The Data Integration Service processes property overrides based on the following priorities:

Mapping custom properties set using
infacmd ms runMapping
with the
-cp
option
Mapping run-time properties for the Hadoop environment
Hadoop connection advanced properties for run-time engines
Hadoop connection advanced general properties, environment variables, and classpaths
Data Integration Service custom properties
