Bridge Parameters
| Parameter Name | Description | Type | Values | Default | Scope |
| Directory | Select a directory that contains Sqoop scripts to import. | DIRECTORY | Mandatory | ||
| File Filter | Specify a search filter for files. Use regular expressions in java format if needed (e.g. '.*\\.sql'). Multiple conditions can be defined by using a space as a separator (e.g. 'file1 file2'). The condition must be escaped with double quotes if it contains any spaces inside (e.g. \"my file.sql\"). Negation can be defined with the preceeding dash character (e.g. '-\\.tar\\.gz'). | STRING | |||
| Miscellaneous | Specify miscellaneous options starting with a dash and optionally followed by parameters, e.g. -connection.cast MyDatabase1="SQL Server" Some options can be used multiple times if applicable, e.g. -connection.rename NewConnection1=OldConnection1 -connection.rename NewConnection2=OldConnection2; As the list of options can become a long string, it is possible to load it from a file which must be located in ${MODEL_BRIDGE_HOME}\data\MIMB\parameters and have the extension .txt. In such case, all options must be defined within that file as the only value of this parameter, e.g. ETL/Miscellaneous.txt GENERAL OPTIONS -m <Java Memory's maximum size> 1G by default on 64bits JRE or as set in conf/conf.properties, e.g. -m 8G -m 8000M -j <Java Runtime Environment command line options> This option must be the last one in the Miscellaneous parameter as all the text after -j is passed "as is" to the JRE, e.g. -j -Dname=value -Xms1G The following option must be set when a proxy is used to access internet (this is critical to access https://repo.maven.apache.org/maven2/ (and exceptionally a few other tool sites) in order to download the necessary third party software libraries. -j -Dhttp.proxyHost=127.0.0.1 -Dhttp.proxyPort=3128 -Dhttps.proxyHost=127.0.0.1 -Dhttps.proxyPort=3128 -Dhttp.proxyUser=user -Dhttp.proxyPassword=pass -Dhttps.proxyUser=user -Dhttps.proxyPassword=pass -jre <Java Runtime Environment full path name> It can be an absolute path to javaw.exe on Windows or a link/script path on Linux, e.g. -jre "c:\Program Files\Java\jre1.8.0_211\bin\javaw.exe" -v <Environment variable value> None by default, e.g. -v var1=value1 -v var2="value2 with spaces" -model.name <model name> Override the model name, e.g. -model.name "My Model Name" -prescript <script name> The script must be located in the bin directory, and have .bat or .sh extension. The script path must not include any parent directory symbol (..). The script should return exit code 0 to indicate success, or another value to indicate failure. For example: -prescript "script.bat arg1 arg2" -cache.clear Clears the cache before the import, and therefore will run a full import without incremental harvesting. Warning: this is a system option managed by the application calling the bridge and should not be set by users. -pppd Create the connections and connection data sets in DI/ETL design models. This feature should only be used when intending to export to another DI/ETL tool. APACHE SQOOP OPTIONS -s <pathname> Path to the key/value pair file that will be used to preprocess the script files and replace shell parameters with the actual values. The path can be escaped with double quotes if it contains spaces or any special characters. The colon character (:) must be escaped with '\' if it is part of a parameter name. The file (referred to by the pathname) must have the following format: key1:value1 "key 2":value2 \:key3withcolon:value3 E.g. -s J:\MIMB\map_of_shell_parameters.txt -e <encoding> This value will be used to load text from the specified script files. By default, UTF-8 will be used. E.g. -e UTF-16 -e UTF-16BE -e US-ASCII -e ISO-8859-1 -p <path> HDFS destination path for tables when --target-dir and --warehouse-dir are not specified. If an imported table is 'country' then the target directory will be '/user/cloudera/country', E.g. -p /user/cloudera |
