--------------------------------
Summary: Expand how table coprocessor jar and dependency path can
be specified
Key: HBASE-14548
URL: https://issues.apache.org/jira/browse/HBASE-14548
Project: HBase
Issue Type: Improvement
Components: Coprocessors
Reporter: Jerry He
Currently you can specify the location of the coprocessor jar in the table
coprocessor attribute.
The problem is that it only allows you to specify one jar that implements the
coprocessor. You will need to either bundle all the dependencies into this
jar, or you will need to copy the dependencies into HBase lib dir.
The first option may not be ideal sometimes. The second choice can be
troublesome too, particularly when the hbase region sever node and dirs are
dynamically added/created.
There are a couple things we can expand here. We can allow the coprocessor
attribute to specify a directory location, probably on hdfs.
We may even allow some wildcard in there.
