Andrew Purtell resolved HBASE-2921.
-----------------------------------
Resolution: Won't Fix
> HBase shell should have a --force-tty option.
> ---------------------------------------------
>
> Key: HBASE-2921
> URL: https://issues.apache.org/jira/browse/HBASE-2921
> Project: HBase
> Issue Type: Improvement
> Components: shell
> Affects Versions: 0.89.20100621
> Reporter: Aditya Acharya
> Original Estimate: 1h
> Remaining Estimate: 1h
>
> When you start the HBase shell from bash, you see the following prompt:
> hbase(main):001:0>
> And typing in "conf" as the command yields the following prompt-related
> information:
> conf.prompt_c="%N(%m):%03n:%i* "
> conf.prompt_i="%N(%m):%03n:%i> "
> conf.prompt_mode=:DEFAULT
> conf.prompt_n="%N(%m):%03n:%i> "
> conf.prompt_s="%N(%m):%03n:%i%l "
> On the other hand, opening the HBase shell as python subprocess yields an
> empty string as the prompt string. Furthermore, sending it the "conf" command
> through a pipe yields the following output:
> conf.prompt_c=nil
> conf.prompt_i=nil
> conf.prompt_mode=:NULL
> conf.prompt_n=nil
> conf.prompt_s=nil
> This occurs because irb checks if stdout is a tty and changes the prompt
> configuration in case it is. It would be very useful for the hbase shell to
> have a --force-tty option that overrides this check.
