Subject [jira] [Updated] (HIVE-10265) Hive CLI crashes on != inequality
Date Wed, 08 Apr 2015 19:24:13 GMT

     [ https://issues.apache.org/jira/browse/HIVE-10265?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Szehon Ho updated HIVE-10265:
-----------------------------
    Attachment: HIVE-10265.patch

Looked at Beeline, the difference is that Jline ConsoleReader is initialized with 'expandEvents'.
 It fixes the issue for me, giving it a try to see if it breaks anything else in CliDriver
tests.

This is also mentioned in a Jline issue: [https://github.com/jline/jline2/issues/96|https://github.com/jline/jline2/issues/96]
