Create Blaze Engine Directories and Grant Permissions

Create the following directories on the Hadoop cluster:

Local services log directory: Configure a local services log directory on all nodes in the cluster and grant permissions to the Blaze user account.
HDFS temporary working directory: Configure a working directory on HDFS for the Blaze engine and grant permissions to the Blaze user account.; This directory is separate from the aggregated persistent log directory.

Verify that a persistent aggregated HDFS log directory exists on the cluster. For example,

/var/log/Hadoop-yarn/apps/Informatica

It is not necessary to create a new directory for persistent logs. Both Blaze instances can use the same persistent aggregated HDFS log directory.
