Note | The -add argument also starts the SAS Embedded Process (same function as -start argument). You are prompted and can choose whether to start the SAS Embedded Process. |
Tip | You can specify the hosts on which you want to install the SAS Embedded Process by using the -hostfile or -host option. The -hostfile or -host options are mutually exclusive. |
See | -hostfile and -host option |
removes the SAS Embedded Process.
Tip | You can specify the hosts for which you want to remove the SAS Embedded Process by using the -hostfile or -host option. The -hostfile or -host options are mutually exclusive. |
See | -hostfile and -host option |
starts the SAS Embedded Process.
Tip | You can specify the hosts on which you want to start the SAS Embedded Process by using the -hostfile or -host option. The -hostfile or -host options are mutually exclusive. |
See | -hostfile and -host option |
stops the SAS Embedded Process.
Tip | You can specify the hosts on which you want to stop the SAS Embedded Process by using the -hostfile or -host option. The -hostfile or -host options are mutually exclusive. |
See | -hostfile and -host option |
provides the status of the SAS Embedded Process on all hosts or the hosts that you specify with either the -hostfile or -host option.
Tips | The status also shows the version and path information for the SAS Embedded Process. |
You can specify the hosts for which you want the status of the SAS Embedded Process by using the -hostfile or -host option. The -hostfile or -host options are mutually exclusive. | |

restarts the SAS Embedded Process.
Tip | You can specify the hosts on which you want to restart the SAS Embedded Process by using the -hostfile or -host option. The -hostfile or -host options are mutually exclusive. |
See | -hostfile and -host option |
specifies the path to the MapReduce home.
specifies the user ID that has Write access to HDFS root directory.
Default | hdfs |
Note | The user ID is used to copy the SAS Embedded Process configuration files to HDFS. |
specifies the name for the SAS Embedded Process user.
Default | sasep |
specifies the name for the SAS Embedded Process group.
Default | sasep |
specifies the full path of a file that contains the list of hosts where the SAS Embedded Process is installed, removed, started, stopped, or status is provided.
Default | If you do not specify -hostfile, the sasep-servers.sh script will discover the cluster topology and use the retrieved list of data nodes. |
Tip | You can also assign a host list filename to a UNIX variable, sas_ephosts_file . export sasep_hosts=/etc/hadoop/conf/slaves |
See | -hdfsuser user-id |
Example | -hostfile /etc/hadoop/conf/slaves |
specifies the target host or host list where the SAS Embedded Process is installed, removed, started, stopped, or status is provided.
Default | If you do not specify -host, the sasep-servers.sh script will discover the cluster topology and use the retrieved list of data nodes. |
Requirement | If you specify more than one host, the hosts must be enclosed in double quotation marks and separated by spaces. |
Tip | You can also assign a list of hosts to a UNIX variable, sas_ephosts . export sasep_hosts="server1 server2 server3" |
See | -hdfsuser user-id |
Example | -host "server1 server2 server3" -host bluesvr |
copies and unpacks the SAS Embedded Process install script file to the host.
Restriction | Use this option only with the -add option. |
Requirement | You must specify either the full or relative path of the SAS Embedded Process install script, tkindbsrv-9.42-n_lax.sh file. |
Example | -epscript /home/hadoop/image/current/tkindbsrv-9.42-1_lax.sh |
copies and unpacks the SAS Hadoop MapReduce JAR files install script on the hosts.
Restriction | Use this option only with the -add option. |
Requirement | You must specify either the full or relative path of the SAS Hadoop MapReduce JAR file install script, hadoopmrjars-9.42-n_lax.sh file. |
Example | -mrscript /home/hadoop/image/current/hadoopmrjars-9.42-1_lax.sh |
specifies options that are passed directly to the SAS Embedded Process. The following options can be used.
specifies what type of trace information is created.
0 | no trace log |
1 | fatal error |
2 | error with information or data value |
3 | warning |
4 | note |
5 | information as an SQL statement |
6 | critical and command trace |
7 | detail trace, lock |
8 | enter and exit of procedures |
9 | tedious trace for data types and values |
10 | trace all information |
Default | 02 |
Note | The trace log messages are stored in the MapReduce job log. |
specifies the TCP port number where the SAS Embedded Process accepts connections.
Default | 9261 |
Requirement | The options in the list must be separated by spaces, and the list must be enclosed in double quotation marks. |
writes the installation output to the specified filename.
specifies the Hadoop version of the JAR file that you want to install on the cluster. The apache-version-number can be one of the following values.
installs the SAS Hadoop MapReduce JAR files that are built from Apache Hadoop 0.23 (sas.hadoop.ep.apache023.jar and sas.hadoop.ep.apache023.nls.jar).
installs the SAS Hadoop MapReduce JAR files that are built from Apache Hadoop 1.2.1 (sas.hadoop.ep.apache121.jar and sas.hadoop.ep.apache121.nls.jar).
installs the SAS Hadoop MapReduce JAR files that are built from Apache Hadoop 0.2.3 (sas.hadoop.ep.apache023.jar and sas.hadoop.ep.apache023.nls.jar).
installs the SAS Hadoop MapReduce JAR files that are built from Apache Hadoop 2.0.5 (sas.hadoop.ep.apache205.jar and sas.hadoop.ep.apache205.nls.jar).
Default | If you do not specify the -version option, the sasep.servers.sh script will detect the version of Hadoop that is in use and install the JAR files associated with that version. For more information, see Installing the SAS Embedded Process and SAS Hadoop MapReduce JAR Files. |
Interaction | The -version option overrides the version that is automatically detected by the sasep.servers.sh script. |
creates a HADOOP_JARS.zip file in the local folder. This ZIP file contains all required client JAR files.
See | For more information, see Copying Hadoop JAR Files to the Client Machine. |
