Sorry I didn't see the comment :(

[~lyubent] that's what you should get. I'm on OSX and using bash completion 1.3 from Homebrew
:
{code}
$ brew list bash-completion
/usr/local/Cellar/bash-completion/1.3/etc/bash_completion.d/ (180 files)
/usr/local/Cellar/bash-completion/1.3/etc/profile.d/bash_completion.sh
/usr/local/Cellar/bash-completion/1.3/etc/bash_completion
{code}
have is a bash-completion function. Tell me the ./nodetool is not executing the bash completion
script :)
To use it, you have to 
- place the file in your bash_completion.d directory (in my case xxxx) :
{code}
$ ls /usr/local/etc/bash_completion.d/node*
/usr/local/etc/bash_completion.d/nodetool
{code}
- add the following (add absolute path if you don't use hombrew) in your ~/.bash_profile :
{code}
if [ -f `brew --prefix`/etc/bash_completion ]; then
    . `brew --prefix`/etc/bash_completion
fi
{code}
- start a new bash session and try :
{code}
nodetool cfh[TAB]
nodetool cfhistograms [TAB][TAB]
pns_fr         system         system_auth    system_traces  test
nodetool cfhistograms system 
HintsColumnFamily      Migrations             batchlog               peer_events         
  schema_columnfamilies  
IndexInfo              NodeIdInfo             hints                  peers               
  schema_columns         
LocationInfo           Schema                 local                  range_xfers         
  schema_keyspaces
{code}

As you see after cfh has been completed to cfhistograms if you add 2 more \[TAB\] you get
the name of keyspaces, and if you add the name of the keyspace system and 2 more \[TAB\] you
get names of column families :)
The first word is the nodetool script from cassandra, not the bash completion script

> it uses cqlsh to get keyspaces and namespaces and could use an environment variable (not
implemented) to get access which cqlsh if authentification is needed. But I think that's really
a good start :)
