installs the SAS Embedded Process.
| Tip | If at a later time you add nodes to the cluster, 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 |
forces the creation
of SAS Hadoop MapReduce JAR files symbolic links in the hadoop/lib folder
during the installation of the SAS Embedded Process.
| Restriction | This argument should be used only for backward compatibility (that is, when you install the July 2015 release of SAS 9.4 of the SAS Embedded Process on a client that runs the second maintenance release of SAS 9.4). |
| Requirement | If you use this argument, you must restart the MapReduce service, the YARN service, or both after the SAS Embedded Process is installed. |
| Interactions | Use this argument in conjunction with the -add argument to force the creation of the symbolic links. |
| Use the -linklib argument after the SAS Embedded Process is already installed to create the symbolic links. | |
| See | Backward Compatibility |
| -linklib |
generates the SAS Embedded Process configuration file in the specified location.
| Default | /sas/ep/config/ep-config.xml |
| Requirement | If you choose a non-default location, you must set the sas.ep.config.file property in the mapred-site.xml file that is on your client machine to the non-default location. |
| Interaction | Use the -epconfig argument in conjunction with the -add or -remove argument to specify the HDFS location of the configuration file. Use the -genconfig argument when you upgrade to a new version of your Hadoop distribution. |
| Tip | Use the -epconfig argument to create the configuration file in a non-default location. |
| See | -genconfig config-filename -force |
specifies the maximum number of parallel copies between the master and data nodes.
| Default | 10 |
| Interaction | Use this argument in conjunction with the -add argument. |
specifies the full path of a file that contains the list of hosts where the SAS Embedded Process is installed or removed.
| Default | The sasep-admin.sh script discovers the cluster topology and uses the retrieved list of data nodes. |
| Interaction | Use the -hostfile argument in conjunction with the -add when new nodes are added to the cluster. |
| 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 or removed.
| Default | The sasep-admin.sh script discovers the cluster topology and uses 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. |
| Interaction | Use the -host argument in conjunction with the -add when new nodes are added to the cluster. |
| 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 |
specifies the user ID that has Write access to HDFS root directory.
| Default | hdfs for Cloudera, Hortonworks, Pivotal HD, and IBM BigInsights |
| mapr for MapR | |
| Interaction | Use the -hdfsuser argument in conjunction with the -add or -remove argument to change or remove the HDFS user ID. |
| Note | The user ID is used to copy the SAS Embedded Process configuration files to HDFS. |
writes the installation output to the specified filename.
| Interaction | Use the -log argument in conjunction with the -add or -remove argument to write or remove the installation output file. |
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 |
generates a new SAS Embedded Process configuration file in the specified location.
| Default | /sas/ep/config/ep-config.xml |
| Requirement | If you choose a non-default location, you must set the sas.ep.config.file property in the mapred-site.xml file that is on your client machine to the non-default location. |
| Interaction | Use the -epconfig argument in conjunction with the -add or -remove argument to specify the HDFS location of the configuration file. Use the -genconfig argument when you upgrade to a new version of your Hadoop distribution. |
| Tip | This argument generates an updated ep-config.xml file. Use the -force argument to overwrite the existing configuration file. |
| See | -epconfig config-filename |
creates a HADOOP_JARS.zip
file in the EPInstall dir/SASEPHome/bin directory.
This ZIP file contains all required client JAR files.
| Restrictions | This argument is not supported for MapR distributions. |
| The -getjars argument is for use only with TKGrid and High-Performance Analytics. It does not gather all of the JAR files that are required for full functionality of SAS software that requires the use of the SAS Embedded Process. Most of the JAR files that are required for full functionality of SAS software are gathered when you install SAS/ACCESS Interface to Hadoop. For more information, see SAS Hadoop Configuration Guide for Base SAS and SAS/ACCESS at http://support.sas.com/resources/thirdpartysupport/v94/hadoop/. | |
| Note | In the July 2015 release of SAS 9.4, the SAS_HADOOP_JAR_PATH environment variable has replaced the need for copying the Hadoop JAR files to the client machine with the exception of High-Performance Analytics. The SAS_HADOOP_JAR_PATH environment variable is usually set when you install SAS/ACCESS Interface to Hadoop. |
| Tip | You can move this ZIP file to your client machine and unpack it. If you want to replace the existing JAR files, move it to the same directory where you previously unpacked the existing JAR files. |
creates SAS Hadoop
MapReduce JAR file symbolic links in the hadoop/lib folder.
| Restriction | This argument should be used only for backward compatibility (that is, when you install the July 2015 release of SAS 9.4 of the SAS Embedded Process on a client that runs the second maintenance release of SAS 9.4). |
| Requirement | If you use this argument, you must restart the MapReduce service, the YARN service, or both after the SAS Embedded Process is installed. |
| Interaction | Use the -linklib argument after the SAS Embedded Process is already installed to create the symbolic links. Use the -link argument in conjunction with the -add argument to force the creation of the symbolic links. |
