Paulo Sequeira commented on HIVE-12612:
---------------------------------------
I agree with Sergio: if any statement fails to execute for some reason, abort
immediately the entire script even if it's a long running one. Many of our
scripts run unattended and for long a long time, and we rely on early failure
detection to be notified that things went wrong and that we should look at them.
> beeline always exits with 0 status when reading query from standard input

> Key: HIVE-12612
> URL: https://issues.apache.org/jira/browse/HIVE-12612
> Project: Hive
> Issue Type: Bug
> Components: Beeline
> Affects Versions: 1.1.0
> Environment: CDH5.5.0
> Reporter: Paulo Sequeira
> Assignee: Reuben Kuhnert
> Priority: Minor
>
> Similar to what was reported on HIVE-6978, but now it only happens when the
> query is read from the standard input. For example, the following fails as
> expected:
> {code}
> bash$ if beeline -u "jdbc:hive2://..." -e "boo;" ; then echo "Ok?!" ; else
> echo "Failed!" ; fi
> Connecting to jdbc:hive2://...
> Connected to: Apache Hive (version 1.1.0-cdh5.5.0)
> Driver: Hive JDBC (version 1.1.0-cdh5.5.0)
> Transaction isolation: TRANSACTION_REPEATABLE_READ
> Error: Error while compiling statement: FAILED: ParseException line 1:0
> cannot recognize input near 'boo' '<EOF>' '<EOF>' (state=42000,code=40000)
> Closing: 0: jdbc:hive2://...
> Failed!
> {code}
> But the following does not:
> {code}
> bash$ if echo "boo;"|beeline -u "jdbc:hive2://..." ; then echo "Ok?!" ; else
> echo "Failed!" ; fi
> Connecting to jdbc:hive2://...
> Connected to: Apache Hive (version 1.1.0-cdh5.5.0)
> Driver: Hive JDBC (version 1.1.0-cdh5.5.0)
> Transaction isolation: TRANSACTION_REPEATABLE_READ
> Beeline version 1.1.0-cdh5.5.0 by Apache Hive
> 0: jdbc:hive2://...:8> Error: Error while compiling statement: FAILED:
> ParseException line 1:0 cannot recognize input near 'boo' '<EOF>' '<EOF>'
> (state=42000,code=40000)
> 0: jdbc:hive2://...:8> Closing: 0: jdbc:hive2://...
> Ok?!
> {code}
> This was misleading our batch scripts to always believe that the execution of
> the queries succeded, when sometimes that was not the case.
> h2. Workaround
> We found we can work around the issue by always using the -e or the -f
> parameters, and even reading the standard input through the /dev/stdin device
> (this was useful because a lot of the scripts fed the queries from here
> documents), like this:
> {code:title=some-script.sh}
> #!/bin/sh
> set -o nounset -o errexit -o pipefail
> # As beeline is failing to report an error status if reading the query
> # to be executed from STDIN, check whether no -f or -e option is used
> # and, in that case, pretend it has to read the query from a regular
> # file using -f to read from /dev/stdin
> function beeline_workaround_exit_status () {
> for arg in "$@"
> do if [ "$arg" = "-f" -o "$arg" = "-e" ]
> then beeline -u "..." "$@"
> return
> fi
> done
> beeline -u "..." "$@" -f /dev/stdin
> }
> beeline_workaround_exit_status <<EOF
> boo;
> EOF
> {code}
