HBase shell prompt is not configured when used as a subprocess
--------------------------------------------------------------
Key: HBASE-2921
URL: https://issues.apache.org/jira/browse/HBASE-2921
Project: HBase
Issue Type: Bug
Components: shell
Affects Versions: 0.89.20100621
Reporter: Aditya Acharya
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
I think this is a bug in the HBase shell. I'm not sure where it occurs, but I
have found that it can be easily patched up by hard-coding the prompt
information into bin/hirb.rb. This seems like the most appropriate fix, as
bin/hirb.rb already modifies the conf for the interpreter.
