Sqoop import from couchbase to hadoop

Question

On Ubuntu, using couchbase 2.5.1, cloudera cdh4, the hadoop plugin for couchbase and oracle jdk 6. Everything installs fine (seemingly), I can work with hadoop and couchbase independently with no problems, but when I try use the plugin as follows

sqoop import --connect http://127.0.0.1:8091/ --table DUMP

I get the following errors

Please set $ACCUMULO_HOME to the root of your Accumulo installation.

Any idea where I'm going wrong? Or what I can do to find out?

Answer 1

It seems the syntax I was using was wrong. Assuming we want to import the beer-sample bucket from couchbase into HDFS, the correct syntax is below, where the bucket name is actually passed as the username.

sqoop import --connect http://localhost:8091/pools --password password --username beer-sample --table DUMP

Answer 2

I dont think you will be able to connect to a couchbase bucket with password using couchbase hadoop plugin. I used to get authentication exception and was never able to solve it. I edited the source code and then I was able to get it working.
