Minor Description
It would save a bunch of googling if we could provide some examples of connection strings directly to beeline help message
Eg:
./bin/beeline --help Usage: java org.apache.hive.cli.beeline.BeeLine -u <database url> the JDBC URL to connect to -r reconnect to last saved connect url (in conjunction with !save) -n <username> the username to connect as -p <password> the password to connect as -d <driver class> the driver class to use -i <init file> script file for initialization -e <query> query that should be executed -f <exec file> script file that should be executed -w (or) --password-file <password file> the password file to read password from --hiveconf property=value Use value for given property --hivevar name=value hive variable name and value This is Hive specific settings in which variables can be set at session level and referenced in Hive commands or queries. --color=[true/false] control whether color is used for display --showHeader=[true/false] show column names in query results --headerInterval=ROWS; the interval between which heades are displayed --fastConnect=[true/false] skip building table/column list for tab-completion --autoCommit=[true/false] enable/disable automatic transaction commit --verbose=[true/false] show verbose error messages and debug info --showWarnings=[true/false] display connection warnings --showNestedErrs=[true/false] display nested errors --numberFormat=[pattern] format numbers using DecimalFormat pattern --force=[true/false] continue running script even after errors --maxWidth=MAXWIDTH the maximum width of the terminal --maxColumnWidth=MAXCOLWIDTH the maximum width to use when displaying columns --silent=[true/false] be more silent --autosave=[true/false] automatically save preferences --outputformat=[table/vertical/csv2/tsv2/dsv/csv/tsv] format mode for result display Note that csv, and tsv are deprecated - use csv2, tsv2 instead --incremental=[true/false] Defaults to false. When set to false, the entire result set is fetched and buffered before being displayed, yielding optimal display column sizing. When set to true, result rows are displayed immediately as they are fetched, yielding lower latency and memory usage at the price of extra display column padding. Setting --incremental=true is recommended if you encounter an OutOfMemory on the client side (due to the fetched result set size being large). --truncateTable=[true/false] truncate table column when it exceeds length --delimiterForDSV=DELIMITER specify the delimiter for delimiter-separated values output format (default: |) --isolation=LEVEL set the transaction isolation level --nullemptystring=[true/false] set to true to get historic behavior of printing null as empty string --addlocaldriverjar=DRIVERJARNAME Add driver jar file in the beeline client side --addlocaldrivername=DRIVERNAME Add drvier name needs to be supported in the beeline client side --showConnectedUrl=[true/false] Prompt HiveServer2s URI to which this beeline connected. Only works for HiveServer2 cluster mode. --help display this message Example: 1. beeline -u jdbc:hive2://localhost:10000 username password 2. beeline -n username -p password -u jdbc:hive2://hs2.local:10012
