<p>This example shows how to use per table classpaths. The example
leverages a
test jar which contains a Filter that supresses rows containing "foo". The
example shows copying the FooFilter.jar into HDFS and then making an Accumulo
table reference that jar.</p>

how to use this feature.</p>
<p>The shell session below shows creating a table, inserting data, and
exporting
the table. A table must be offline to export it, and it should remain offline
for the duration of the distcp. An easy way to take a table offline without
interuppting access to it is to clone it and take the clone offline.</p>
