SPD Server 5.2 and later
provides support for SPD Server tables in Hadoop domains. The Hadoop
environment requires additional restrictions if you want to share
SPDSBASE processes.
To access the Hadoop
cluster, the SPD Server user proxy forks and executes the SAS Java
proxy (JProxy) process. The SAS Java proxy process provides the Java
Virtual Machine (JVM) environment that is required to communicate
with the Hadoop cluster. A Java proxy is configured to access only
one Hadoop cluster.
In order for Hadoop
LIBNAME domains to share the same user proxy, the LIBNAME domains
must have the same values for the following options:
-
HADOOPCFG= and HADOOPJAR= must
have the same values
-
HADOOPUSER= and HADOOPREALM= options
must have the same values
