Subject [jira] [Commented] (HIVE-6758) Beeline doesn't work with -e option when started in background
Date Mon, 27 Oct 2014 04:38:33 GMT

    [ https://issues.apache.org/jira/browse/HIVE-6758?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14184819#comment-14184819
] 

Thejas M Nair commented on HIVE-6758:
-------------------------------------

With this change, beeline does not work with the arrow keys. (scroll up/down, right/left).
 The shell condition in the patch does not identify foreground correctly, and as  a result
it always sets this env variable. I tried the following on bash in mac and linux. 

{noformat}
$ cat /tmp/t.sh
#!/usr/bin/env bash 
if [[ ! $(ps -o stat= -p $$) =~ + ]]; then
  echo "background"
  export HADOOP_CLIENT_OPTS="$HADOOP_CLIENT_OPTS -Djline.terminal=jline.UnsupportedTerminal"
fi

$  /tmp/t.sh
background
{noformat}

The shell command pasted by Brock works correctly

> In hive CLI you could easily integrate its use into a script and back ground the process
like this: 
> hive -e "some query" &
> Beeline does not run when you do the same even with the -f switch.
