generateHadoopConnectionFromHiveConnection

generateHadoopConnectionFromHiveConnection

Generates a Hadoop connection from a Hive connection enabled to push mapping logic to the Hadoop cluster. The generated Hadoop connection inherits the permissions of the Hive connection.
The infacmd generateHadoopConnectionFromHiveConnection uses the following syntax:
generateHadoopConnectionFromHiveConnection
       
<-DomainName|-dn> domain_name
        
<-UserName|-un> user_name
        
<-Password|-pd> password
        
[<-SecurityDomain|-sdn> security_domain]
        
[<-ResilienceTimeout|-re> timeout_period_in_seconds]
        
[<-ConnectionPrefix|-p> connection_prefix, default value is AutoGen_. Not used if the target connection name is provided.]
        
[<-SourceConnectionName|-scn> hive_connection_name. If you do not enter the Hive connection name, the command generates a Hadoop connection from all Hive connections enabled for pushdown.]
        
[<-TargetConnectionName|-tcn> hadoop_connection_name. Used if the Hive connection name is provided.]
        
[<-ConflictResolution|-cr> The conflict resolution strategy for a connection generation task performed previously on the source connection(s). Valid options are skip, replace, or rename.]
The following table describes the generateHadoopConnectionFromHiveConnection options and arguments.
Option Argument Description
DomainName
-dn
domain_name
Required. Name of the Informatica domain. You can set the domain name with the -dn option or the environment variable INFA_DEFAULT_DOMAIN. If you set a domain name with both methods, the -dn option takes precedence.
UserName
-un
user_name
Required if the domain uses Native or LDAP authentication. User name to connect to the domain. You can set the user name with the -un option or the environment variable INFA_DEFAULT_DOMAIN_USER. If you set a user name with both methods, the -un option takes precedence.
Optional if the domain uses Kerberos authentication. To run the command with single sign-on, do not set the user name. If you set the user name, the command runs without single sign-on.
Password
-pd
password
Required if you specify the user name. Password for the user name. The password is case sensitive. You can set a password with the -pd option or the environment variable INFA_DEFAULT_DOMAIN_PASSWORD. If you set a password with both methods, the password set with the -pd option takes precedence.
SecurityDomain
-sdn
security_domain
Required if the domain uses LDAP authentication. Optional if the domain uses native authentication or Kerberos authentication. Name of the security domain to which the domain user belongs. You can set a security domain with the -sdn option or the environment variable INFA_DEFAULT_SECURITY_DOMAIN. If you set a security domain name with both methods, the -sdn option takes precedence. The security domain name is case sensitive.
If the domain uses native or LDAP authentication, the default is Native. If the domain uses Kerberos authentication, the default is the LDAP security domain created during installation. The name of the security domain is the same as the user realm specified during installation.
ResilienceTimeout
-re
timeout_period_in_seconds
Optional. Amount of time in seconds that infacmd attempts to establish or re-establish a connection to the domain. If you omit this option, infacmd uses the timeout value specified in the INFA_CLIENT_RESILIENCE_TIMEOUT environment variable. If no value is specified in the environment variable, the default of 180 seconds is used.
ConnectionPrefix
-p
connection_prefix
Prefix for the generated Hadoop connection. Default value is AutoGen_. Not used if the target connection name is provided. If the target connection name is not provided, the generated Hadoop connection inherits the name of the Hive connection with the case insensitive string Hive changed to Hadoop.
SourceConnectionName
-scn
hive_connection_name
Connection name for the Hive source. If you do not enter the Hive connection name, the command generates a Hadoop connection from each Hive connection enabled for pushdown.
When you enter the source connection name without providing the target connection name, the command selects a name for the Hadoop connection.
TargetConnectionName
-tcn
hadoop_connection_name
Connection name for the Hive target. Used if the Hive connection name is provided.
When you enter the target connection name, and the target connection name already exists, the command fails with a message that states the connection already exists.
ConflictResolution
-cr
n/a
The conflict resolution strategy for a connection generation task performed previously on the source connection. A conflict arises when an earlier generated Hadoop connection of the target type is found. You can specify the following options:
  • replace. The earlier generated Hadoop connection will be replaced.
  • rename. Generate another Hadoop connection from the Hive connection enabled for pushdown. To avoid a naming conflict, index is appended to the Hadoop connection name.
  • skip. Default resolution type. If a Hadoop connection is already generated from the corresponding Hive connection enabled for pushdown, the Hadoop connection is not generated again.
