Subject [jira] [Commented] (HIVE-14389) Beeline should not output query and prompt to stdout
Date Fri, 06 Oct 2017 18:38:01 GMT

    [ https://issues.apache.org/jira/browse/HIVE-14389?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16195002#comment-16195002
] 

Vihang Karajgaonkar commented on HIVE-14389:
--------------------------------------------

Thats the behavior which was fixed by this patch. The query text should not be mixed with
the results because if you want to process the results (to load as data somewhere else for
example)  then you will have to manually clean it up by removing the query text. You can always
add the query text to your results file if really want by redirecting the stderr to the same
file using {{beeline --verbose=true -f hadoop_query.hql > test.txt 2>&1}}

> It seems that the Beeline prints the query along with the results in the stdout when
a script file is passed. The output file in the example below needs to only have the results
and not the query.

> .vihang-MBP:bin vihang$ ./beeline --showheader=false --outformat=tsv2 -u "jdbc:hive2://localhost:10000"
-f /tmp/query.sql > /tmp/query.out 2> /tmp/query.err
> OK
> $ cat /tmp/query.out
> 1: jdbc:hive2://localhost:10000/default> select * from likes limit 4;

> A lot of people use HiveCLI and in order to transition from HiveCLI scripts to Beeline,
this needs to be taken care of. The output files generated by beeline should contain only
the results and nothing else.
> Similarly, when not in silent mode, query are being printed out on stdout, which is adding
garbage along with results, as just like HIVE CLI does, users would like to have only the
results on stdout, not errors/debugging info/etc, like the full query. 
> Query could be printed out, no problem, as long as it is not on stdout (with results),
instead, it must be printed out along with the debugging info.
