Subject [jira] [Commented] (HIVE-6694) Beeline should provide a way to execute shell command as Hive CLI does

    [ https://issues.apache.org/jira/browse/HIVE-6694?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14045116#comment-14045116

Xuefu Zhang commented on HIVE-6694:
-----------------------------------

[~brocknoland] Just make sure that I understand correctly. Did you mean I need to check if
e.getLocalizedMessage() is null? Would you like to see something like the following:
{code}
String msg = e.getLocalizedMessage();
if (msg == null)
  msg = "unknown cause"
beeLine.error("Failed to execute Shell command: " + msg);
{code}

> Hive CLI allows a user to execute a shell command using ! notation. For instance, !cat
myfile.txt. Being able to execute shell command may be important for some users. As a replacement,
however, Beeline provides no such capability, possibly because ! notation is reserved for
SQLLine commands. It's possible to provide this using a slightly syntactic variation such
as !sh cat myfilie.txt.
