[jira] [Commented] (SQOOP-2764) Sqoop2: Sqoop shell history is no longer working

["Dian Fu (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SQOOP-2764?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15075773#comment-15075773 ] 

Dian Fu commented on SQOOP-2764:
--------------------------------

The reason to this issue is that we upgrade Groovy(1.8.5->2.4.0) and Jline (0.9.94->2.13). For the {{history}} function in Jline, it will flush the history command to file each time a new command is executed in version 0.9.94 [1]. While in Jline 2.x, this behavior has been changed and it requires application to do that flush [2]. But Groovy (which uses Jline) doesn't make changes accordingly.

> It seems that shell history is no longer working. E.g when I run shell once and run some commands:
> {code}
> $ /bin/sqoop.sh client
> Setting conf dir: ./bin/../conf
> Sqoop home directory: /root/sqoop-2.0.0-SNAPSHOT-bin-hadoop200
> Sqoop Shell: Type 'help' or '\h' for help.
> sqoop:000> show connector
> ...
> sqoop:000>
> {code}
> Then exit the shell and re-enter it, pressing arrow up won't show any past commands.
