Subject Re: Hbase DeleteAll is not working
Date Mon, 14 May 2012 17:58:41 GMT
Please don't cross-post, your question is about HBase not MapReduce
itself so I put mapreduce-user@ in BCC.

0.20.3 is, relatively to the age of the project, as old as my
grand-mother so you should consider upgrading to 0.90 or 0.92 which
are both pretty stable.

I'm curious about the shell's behavior you are encountering. Would it
be possible for you to show us the exact trace of what you are doing
in the shell?

To be clear, here's what I'd like to see:

- A get of the row you want to delete. Feel free to zero out the values.
- A deleteall of that row.
- Another get of that row.
- A delete of a column (that should work according to your email).
- A last get of that row.
