-Re: problem installing accumulo

I guess a little of both. In the Enron email set I have a bunch of folders
representing people. Each folder has subfolders that equate to mailboxes
(inbox, sent_mail, etc...). Each mailbox simply contains text files named
1, 2, 3, 4 that equate to an individual email.
Each email is a text file that if easy to parse into specific fields. I
want to place those emails in accumulo and run some simple MapReduce for
the demo. Similar to what I saw in some *Cloudbase *training last year.
What I didn't remember is how the tables were arranged.
I was just going to make each email, regardless of mailbox as a row in
accumulo and make make the mailbox and owner separate columns (or column
qualifier to be more specific). My issue is the To and CC fields. Each can
be a list. I was thinking of making the column family to and the column
qualifier 1,2,3, ...). I could also make the column qualifier for the to
family the actual value "[EMAIL PROTECTED]". I wasn't exactly sure of the best
Each email has a Message_ID and so far I think they are unique. If not I
can generate a unique ID.
Again this will be for a simple demo where people may want to search from
some person, to some person and maybe for specific terms in the body of the
Hope this gives a good idea of what I am trying to do. Feel free to ask any
other questions you may have if I wasn';t clear enough. Again I have more
experience working with existing structures. I am trying t use this
experience to learn a little about how to organize the data.
thanks in advance,
