---------------------------------
Summary: Beeline gives evasive error message for any unrecognized
command line arguement
Key: HIVE-6652
URL: https://issues.apache.org/jira/browse/HIVE-6652
Project: Hive
Issue Type: Bug
Affects Versions: 0.12.0, 0.11.0, 0.13.0
Reporter: Xuefu Zhang
Assignee: Xuefu Zhang
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
-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
{code}
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 and HIVE-6110. 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.
