Hi Revan,
You likely don't want to use the shell as a means to ingest as you will
get abysmal performance (each record you insert will create a
batchwriter, write one record and close the batchwriter).
But, if bad performance is ok, using a large file of shell commands with
the `shell -f ..` option you noted would work. This would be slightly
more efficient as you said (not re-authenticating with Accumulo for
every insert. Before you start insert records, you can switch to a table
context using the `table <tablename>` command.
Feel free to open an issue on JIRA to add a "-t" option to the insert
command as this would be a good addition

Hi,
I'm an Italian student and i'm going to be graduated having thesis about
using accumulo.
I've developed a little java application that reads LOGS in a .json file and
insert them into accumulo.
In my virtual machine my app's insert/sec score is about 6'000.
I see that there are some bench test that scores about 50'000 in my VM.
(It's in $ACCUMULO_HOME/test/system/* folder.)
Those test use the shell call to insert a large amount of data.
So I think that i could write all my insert using an accumulo-shell call in
my app.
I've seen that i can execute that command:
./bin/accumulo shell -u username -p passw -e "insert row fam qual val [vis]
[timestamp]"
but there is a problem: i need to set up the table with the command table
(infact insert command has not -t
option).
So there is any way to execute two commands in a row into accumulo shell? i
tried with&& ; and other separator but with no success.
The other option that i have is to write a big command file with all
commands that i need and send it to accumulo shell using the command
./bin/accumulo shell -f<file>
it may be a better solution cause i'll connect to accumulo just one time
(and not for every insert)...
Any suggest?
Thank you everybody and sorry for my bad english.
Revan
