Hi,
 
I was trying to run HBase in an environment where there is no bash. Will it stll work fine?
 
Thanks,
Sumit

Hi Sumit,

Could you please provide more details about this environment? What
operating system are you using? HBase is most frequently deployed on Linux,
and many developers run it on Mac OS X locally for testing. It is also
possible to run HBase on Windows using Cygwin (
http://hbase.apache.org/docs/r0.20.6/cygwin.html) -- Cygwin provides a
UNIX-like environment on Windows, which includes bash.

Thanks,
--Mikhail

A lack of 'bash' specifically (meaning, you are still using another shell?) may be OK, you'd lose out on using some shipped scripts to start and stop clusters. But if you are running on non-*nix platforms, there could be issues in running HDFS.

Hi Mikhail,
 
I am installing HBase on an AIX machine. It has ksh and sh but no bash. Hence when it encounters #!/usr/bin/env bash the script gives an error.  bash: A file or directory in the path name does not exist.
 
How is #!/usr/bin/bash different from #!/usr/bin/env bash
 
As Harsh says that the scripts wont run - they are not running. In such a case 14 scripts from HBase, a similar set for Hadoop will need to be changed and any other related sub-project in future. Are there any more changes that will be needed?
 
Thanks,
Sumit.

First don't use AIX.
It's nothing against IBM, except that you will find that you are going to run unsupported unless you run the apache release and IBM is selling you support and you will end up with a derivative.

Second, convince a bunch of open source contributors to switch to ksh.
(good luck on that.)

Third, you could install bash on AIX, good luck with that.

The point is that either you are going to have to do a lot of extra work, ending up with a derivative, all on a system which you are trying to learn.

Note that you could install bash...
However you asked whats the difference between /usr/bin/bash and /usr/bin/env bash.
Good question.

Assuming that /usr/bin/bash exists, it would imply that you already have bash on the system.

So if you first type in /usr/bin/bash what happens?

If you get a bash shell prompt, then try and run the script. If it runs, then you need to change your user shell.

Hi Michael,

Thanks for the impact analysis of running HBase on AIX.

There is no /usr/bin/bash on the system. But I am not clear of the difference between  #!/usr/bin/bash and #!/usr/bin/env bash

Warm Regards,
Sumit

Hi Sumit,

"#!/usr/bin/env bash" will search for bash on the configured PATH, while
#!/usr/bin/bash assumes that the bash binary is in /usr/bin. In any way,
bash should probably run fine on AIX, even if you have to compile it from
sources. I suggest that you install bash into /bin/bash or /usr/bin/bash,
though.

Thanks,
--Mikhail
