Create Blaze Engine Directories and Grant Permissions

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.
