Create Blaze Engine Directories and Grant Permissions

Create the following directories on the Hadoop cluster:

Local services log directory: Create a local services log directory on all nodes in the cluster and grant permissions to the Blaze user account. The hadoopEnv.properties file on the domain contains an entry for this directory. The file uses an environment variable, $HADOOP_NODE_INFA_HOME, that gets set to the Big Data Management installation directory. The default installation directory is
/opt/Informatica
. For example, run the following commands:
hadoop fs mdkir -p /opt/Informatica/blazeLogs
hadoop fs -chmod 777 /opt/Informatica/blazeLogs; If you use a different directory name, you must update the following property in the hadoopEnv.properties file:
infagrid.node.local.root.log.dir
HDFS temporary working directory: Create a working directory on HDFS for the Blaze engine and grant permissions to the Blaze user account. For example, run the following commands:
hadoop fs mkdir -p /blaze/workdir
hadoop fs -chmod 777 /blaze/workdir; When you configure connection properties, you provide the path to this directory. Alternatively, you can create this directory when you create the connection.
This directory is separate from the aggregated persistent log directory.
