Xuefu Zhang updated HIVE-6652:
------------------------------
Attachment: HIVE-6652.patch
With the attached patch, Beeline will emit:
{code}
beeline abc
Unrecognized argument: abc
Usage: java org.apache.hive.cli.beeline.BeeLine
-u <database url> the JDBC URL to connect to
-n <username> the username to connect as
-p <password> the password to connect as
-d <driver class> the driver class to use
-e <query> query that should be executed
-f <file> script file that should be executed
--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/csv/tsv] format mode for result display
--isolation=LEVEL set the transaction isolation level
--nullemptystring=[true/false] set to true to get historic behavior of
printing null as empty string
--help display this message

> Key: HIVE-6652
> URL: https://issues.apache.org/jira/browse/HIVE-6652
> Project: Hive
> Issue Type: Bug
> Affects Versions: 0.11.0, 0.12.0, 0.13.0
> Reporter: Xuefu Zhang
> Assignee: Xuefu Zhang
> Attachments: HIVE-6652.patch

>
> For any unrecognized command line argument, Beeline emits a warning message
> that's evasive and meaningless. For instance:
> {code}
> beeline abc
> abc (No such file or directory)
> Beeline version 0.14.0-SNAPSHOT by Apache Hive
> ...
> beeline -hh
> -hh (No such file or directory)
> {code}
> The error seeming suggests that Beeline accepts an argument as a file name.
> However, neither Beeline doc nor command line help indicates there is such an
> option.
> {code}
> beeline --help
> Usage: java org.apache.hive.cli.beeline.BeeLine
> -u <database url> the JDBC URL to connect to

> Further research shows that this is a residual from SQLLine from which
> Beeline is derived, which allows user to specify a property file based on
> which SQLLine can make a DB connection.
> While this might be useful, this isn't documented and has caused a lot of
> confusions. And it's the root cause for quite a few problems such as those
> described in HIVE-5677. HIVE-6173 had the same symptom, which uncovered
> another problem.
> Thus, I'd suggest we disable this option. If it's desirable to have this
> option, then we need at least corresponding documentation plus better error
> message.
